Marine Zulu Gathering

Looking out from the Woods Hole Oceanographic Institute, taken on the 1st October 2017

This week I’m at the Integrated Marine Biosphere Research (IMBeR) IMBIZO5 event at the Woods Hall Oceanographic Institute. IMBIZO is a Zulu word meaning a meeting or gathering called by a traditional leader and this week a group of marine scientists have heeded the call.

The fifth meeting in the IMBIZO series is focussing on Marine Biosphere Research for a Sustainable Ocean: Linking ecosystems, future states and resource management. Its aim is help understand, quantify and compare the historic and present structure and functioning of linked ocean and human systems to predict and project changes including developing scenarios and options for securing or transitioning towards ocean sustainability.

Woods Hole is located in the US state of Massachusetts. It is well-known centre of excellence in marine research and the world’s largest private, non-profit oceanographic research institution. Despite my career travels, it was somewhere I had never visited before. So this was a great opportunity to see a place I had read a lot about, and to meet people from a variety of marine disciplines.

After my Saturday morning flight to Boston, my first challenge was to find the fantastically named ‘Peter Pan Bus’ for the two hour drive to Falmouth, a town near the Woods Hole Institute. Regular readers will spot that this is the second Falmouth I’ve visited this summer, as I gave talk in the Cornish version in July. It’s actually slightly odd to hear familiar place names such as Plymouth, Barnstaple and Taunton in a different country. Carrying my poster also singled me out as an IMBIZO attendee, Lisa stopped to give me a lift to hotel as I walked through the town – not sure that would happen back in the UK!

I needed to be up early on Sunday as we had an Infographics workshop led by Indi Hodgson-Johnston from the University of Tasmania. We learnt about how to work through the creative process, starting with choosing a theme through to defining 4 to 8 factoids (1 to 2 sentences with a single message) to finally bringing the factoids and accompanying images together into the infographic.

Interestingly, Indi highlighted that only 20% of the people who start watching a video on social media are still watching after 15 seconds! In addition, most watch without sound. The key message for me was to make very short videos with subtitles. Or better still make infographics.

The workshop itself began on Monday with three keynotes. The first by Edward Allison, of the University of Washington, focussed on the limits of prediction and started by defining terms and their time scales:

  • Forecasts: from minutes to weeks e.g. weather forecasting
  • Predictions: from months to years e.g. climate variability
  • Scenarios: front decades to centuries e.g. climate change

As we go from forecasts to predictions uncertainty increases, and further still when we move to scenarios. Therefore, we need to be clear about the limits of what’s possible. Secondly, whilst we’ve become good at understanding bio-chemical and physical processes, uncertainty grows as we move to modelling ecosystems and human interactions.

Mary Ann Moran from the University of Georgia spoke about the ‘Metabolic diversity and evolution in marine biogeochemical cycling and ocean ecosystem processes’ and emphasised the linkage between phytoplankton and microbes, and how omics (fields such as metabolomics, (meta)-proteomics and -transcriptomics) can help us to understand this complex relationship.

The final keynote was by Andre Punt from the University of Washington on ‘Fisheries Management Strategy Evaluation’. It looked at how we move from data on fish catches to deciding what a sustainable quota is for managing fishing stocks. Management strategy evaluation involves running multiple simulations to compare the relative effectiveness of achieving management objectives i.e., a “fisheries flight simulator”. Given the different stakeholders in this debate will often have opposing requirements; the wrong choice can have catastrophic effects on either fish populations or livelihoods. Hence, this approach often involves finding the least worst solution.

The workshop streams began in the afternoon and I’m in one focussing on ‘Critical Constraints on Prediction’. We all gave 3 minute lightening talks to introduce ourselves and started the discussion on the topic of uncertainties and how these can be reduced in future projections.

Exploring this topic over the next few days is going to be really interesting!

Outstanding Science!

It’s British Science Week! Co-ordinated by the British Science Association (BSA) and funded by the UK Government through the Department for Business, Energy and Industrial Strategy, it’s a celebration of science, engineering, technology and maths – often referred to as STEM.

The week runs from 10th to the 19th March which technically makes it a ten day festival – a slightly concerning lack of precision for a celebration of these subjects! There are events taking place all over the UK, and you can see here if there are any local to you. For us, there are nine events taking place in Plymouth. Highlights include:

  • Be a Marine Biologist for A Day running on the 16th and 17th at the Marine Biological Association
  • Science Week Challenge – Cliffhanger: On 17th of March teams of students from Secondary Schools across Plymouth will compete to design and build a machine to solve a problem.
  • Dartmoor Zoological Park running a STEM careers day. Although, sadly you’ve already missed this as it took place on Tuesday!

All of these, and the many others across the country, are fantastic for promoting, educating and inspiring everyone to get involved with STEM subjects and careers. Regularly readers know this is something that we’re very keen on at Pixalytics. Eighteen months ago we published a book, ‘Practical Handbook of Remote Sensing’, which aims to take complete beginners through the process of finding, downloading, processing and visualising remote sensing satellite data using just their home PC and an internet connection.

We were delighted to find out recently that our book has been chosen an Outstanding Academic Title (OAT) of 2016 by Choice, a publication of the Association of College & Research Libraries, a division of the American Libraries Association.

OAT’s are chosen from titles reviewed in Choice over the last year, and selected books demonstrate excellence in scholarship, presentation and a significant contribution to the field. The reviewer’s comments are integral to this process. Someone from San Diego State University reviewed our book last August and their comments included:

  • ‘a unique approach to the presentation of the subject’
  • ‘This book is successful in achieving its aim of making the science of remote sensing accessible to a broad readership.’
  • ‘Highly recommended. All library collections’

OAT’s are a celebration of the best academic books and Choice selected 500 titles out of 5,500 they reviewed last year. We’re very proud to have been included in this list.

Everyone can, and should, get involved in science. So why not go to one of the British Science Week events local to you, or if not you could always read a book!

Plymouth Student’s Shot at Space!

From left to right: Fraser Searle (President), Sam Kennerley (Secretary) of Plymouth University Space Society, with the equipment to launch the balloon.

Plymouth University’s Space Society plans to send a small bottle of gin ‘into space’ attached to a weather balloon at the end of March.

The aim is to send the bottle 100,000 feet above the Earth, equivalent to 30 kilometres, and then bring it back safely. On its return, in true student fashion, they intend to use it to drink a few ‘space cocktails’!

The idea for launching the weather balloon began last summer when Fraser Searle and Nick Hardacre, who lead the Space Society at Plymouth University, were looking for ways to create interest in space in the local community. They originally hoped to send a bottle of local gin up, but soon found the challenges of working in a sub zero environment. It would have taken a balloon one and half times the size of the current one and double the volume of helium, so they changed to the shot glass.

They’ll also be attaching cameras and tracking equipment to the six metre diameter balloon to record and monitor the journey. The students have a roller coaster of emotions at the moment as Fraser explained, “We’re feeling excited, but I do get waves of nerves as to whether the glass and the cameras will return unharmed. We’re also wondering if the pictures and videos will be clear.”

Technically, the weather balloon won’t get into space. It should reach the upper half of the stratosphere, an area known as near space. As this area stretches from 20km to 100km above the Earth, ‘near’ is a relative term.

Pixalytics got involved with the project before Christmas, when we helped with sponsorship to enable the students to finish purchasing the necessary equipment. We’re also hoping to provide support in reviewing and interpreting the images the cameras collect on the journey. It’ll be interesting to compare what the weather balloon sees, with what various satellite imagery shows.

We’re strong supporters of events that encourage students and early career scientists to enhance their understanding of remote sensing, space and science. We sponsor student conferences and prizes that take place in the UK. So, it’s fantastic to get involved in something much closer to home.

Launching a weather balloon requires permission from the Civil Aviation Authority, and is also highly weather dependent. A planned launched at the end of January had to be abandoned as the balloon was likely to end up in Portsmouth or Calais harbour.

However, the team have once again got the relevant permissions to try again this coming week. The exact launch date will depend on the wind and weather patterns around Plymouth, which are always fairly turbulent. Fraser said, “We’ll be glued to the online predictors to find a launch slot.”

This is great local project for Plymouth, and we’re pleased to be able to support it. We have our fingers crossed for suitable weather, but only time will tell if they manage to conquer space!

Spinning Python in Green Spaces

As students, we are forever encouraged to find work experience to develop our real-life skills and enhance our CV’s. During the early period of my second year I was thinking about possible work experience for the following summer. Thanks to my University department, I was able to find the Space Placements in INdustry (SPIN) scheme. SPIN has been running for 4 years now, advertising short summer placements at host companies. These provide a basis for which students with degrees involving maths/physics/computer science can get an insight into the thriving space sector. I chose to apply to Pixalytics, and three months later they accepted my application in late March.

Fast forward a few more months and I was on the familiar train down to Plymouth in my home county of Devon. Regardless of your origin, living in a new place never fails to confuse, but with perseverance, I managed to settle in quickly. In the same way I could associate my own knowledge from my degree (such as atmospheric physics, and statistics) to the subject of remote sensing, a topic which I had not previously learnt about. Within a few days I was at work on my own projects learning more on the way.

My first task was an informal investigation into Open data that Plymouth City Council (PCC) has recently uploaded onto the web. PCC are looking for ways to create and support innovative business ideas that could potentially use open data. Given their background, Pixalytics could see the potential in developing this. I used the PCC’s green space, nature reserve and neighbourhood open data sets and found a way to calculate areas of green space in Plymouth using Landsat/Sentinel 2 satellite data to provide a comparison.

There were a few challenges to overcome in using the multiple PCC data sets as they had different coordinate reference systems, which needed to be consistent to be used in GIS software. For example, the Nature Reserves data set was partly in WGS84 and partly in OSGB 1936. Green space is in WGS 84 and the neighbourhood boundaries are in OSGB 1936. This meant that after importing these data sets in GIS software, they wouldn’t line up. Also, the green space data set didn’t include landmarks such as the disused Plymouth City airport, and large areas around Derriford Hospital and Ernsettle. Using GIS software I then went on to find a way to classify and calculate areas of green space within the Plymouth city boundary. The Sentinel-2 which can be seen above, has a higher spatial resolution and allowed me to include front and back gardens.

My green space map for 2016 created from Sentinel 2 data is the most accurate, and gives a total area of green space within the Plymouth neighbourhood boundary of 43 square kilometres, compared with 28 square kilometres that PCC have designated within their dataset. There are some obvious explainable differences, but it would be interesting to explore this deeper.

My second project was to write computer code for the processing and mosaicking of Landsat Imagery. Pixalytics is developing products where the user can select an area of interest from a global map, and these can cause difficult if the area crosses multiple images. My work was to make these images as continuous as possible, accounting for the differences in radiances.

I ended up developing a Python package, some of whose functions include obtaining the WRS path and row from an inputted Latitude and Longitude, correcting for the difference in radiances, and clipping and merging multiple images. There is also code that helps reduce the visual impact of clouds on individual images by using the quality band of the Landsat 8 product. This project took up most of my time, however I don’t think readers would appreciate, yet alone read a 500 line python script, so this has been left out.

I’d like to take this opportunity to thank Andrew and Samantha for giving me an insight into this niche, and potentially lucrative area of science as it has given me some direction and motivation for the last year of my degree. I hope I’ve provided some useful input to Pixalytics (even if it is just giving Samantha a very long winded Python lesson), because they certainly have done with me!

‘On the road, you will face many stumbling blocks, twists, and turns… You may never know how far the road will take you.’ **

In my case, the road brought me to Plymouth, a city on the south coast of Devon, England, a magical place with great history and outstanding views.

What I am doing here? Well, I am pursuing my dream of becoming a GIS and Remote Sensing Specialist by doing an internship through the Erasmus + programme at a local company called Pixalytics. My mentor is Dr. Samantha Lavender, is a great professional with vast experience in this field, She is also the Chairman of the British Association of Remote Sensing Companies and former Chairman of the Remote Sensing & Photogrammetry Society. For me, this is about more than just getting a grade, earning credit, or making money; this is an opportunity to learn, ask questions, and impress with my eagerness.

Finding this internship was easy for me. With a short search on Google I found this Pixalytics blog, where a previous student here had posted her impressions and thoughts on the company. I immediately said “This worth trying!” In the next moment I opened my email started writing, I sent wrote emails to multiple addresses, to make sure my message reached the target. After just two days, I received an answer from Mr. Andrew Lavender and it was positive!

I was very happy and because I knew the departure papers would take over a month to be completed, I immediately started doing them. All of this happened at the end of September. After my papers were done, I bought my flight ticket to Luton Airport, then a bus to London and then onto Plymouth. I arrived on December 5th and so, like the previous student, here I am posting my own impressions and thoughts on the Pixalytics blog page.

My first day at Pixalytics started pretty badly, I got lost and arrived a little late. I now remind myself each morning to turn left, not right, when I get off the bus. I got a short introduction to the building where the company is located, and my office for the next three months, which by the way looks very good. The office has a professional, but relaxed, atmosphere and I soon started working, one of my first tasks being the downloading of Sentinel-2A data, which proved a very difficult one due to slow data speeds and functionality of the ESA Data Hub.

Over the next three months, I am expecting to assist Pixalytics in developing their agritech products, explore the potential of Sentinel-2A data and I will be doing my own research into Urban Sprawl in Romania. I am hoping to have the opportunity to present my research at a conference during my placement.

It has been over a week now since I came to Plymouth and I feel great, working at Pixalytics is a great opportunity for my career and I will take full advantage of this. I strongly recommend all students who want to burst their work experience and who want to see what it is like to be in a professional business environment, to search for Erasmus+ placement offers as I did. You will not regret it!

Sentinel-2A Data Released Into The Wild

Sentinel -2A is already producing some fantastic images, and last week ESA announced the availability of Sentinel-2A orthorectified products in the Sentinel Data Hub. This will enable Sentinel-2 data to be accessed more widely, although as we found out this week there are still a few teething problems to sort out.

At the top of the blog is a stunning image of the Chinese city of Qingdao, in the eastern Shangdong province. The false colour image shows the city of Qingdao and the surrounding area with the centre dominated by Jiaozhou Bay, which is natural inlet to the Yellow Sea. The bay is 32 km long and 27 km wide, and generally has a depth of around ten to fifteen metres; although there are deeper dredged channels to allow larger ships to enter the local ports. The bay itself has decreased by around 35% since 1928, due to urban and industrial growth in the area.

There is a tenuous linguistic link between Plymouth, where Pixalytics is based, and Qingdao. Plymouth is branded as Britain’s Ocean City and Qingdao is home to the Ocean University of China. Qingdao does however, have a much greater claim to fame. It is home to the World’s Longest Bridge. The Jiaozhou Bay Bridge is 42 km long and transects the bay. It is clearly visible on the satellite image, although you might not be able to see it on the thumbnail image at the top of the blog. Therefore, if you look at the subset to the right, you should be able to see bridge clearly and boats on the bay.

Now Sentinel-2A data has been released into the Sentinel Data Hub, images like this are waiting for everyone in the world to discover. We’ve been testing Sentinel-2A data for a few months already, as were part of the community who gave feedback to ESA on the quality of the data. Sentinel-2A carries a Multispectral Imager (MSI) that has 13 spectral bands with 4 visible and near infra-red spectral bands with a spatial resolution of 10 m, 6 short wave infrared spectral bands with a spatial resolution of 20 m and 3 atmospheric correction bands with a spatial resolution of 60 m. When the identical Sentinel-2B is launched in late 2016, the pair will offer a revisit time of only 5 days.

The data from Sentinel-2A forms part of the Copernicus program and is freely available to use, as such it is bound to be very popular. So popular in fact, we found it difficult to get on the Data Hub this week, with slow data speeds and a few elements of the functionality not working efficiently. Although, we’re sure that these will be resolved quickly. Also, there are user guides and tutorials available on the website to help people use the data hub.

The Sentinel-2A data release, following on from the microwave data from Sentinel-1, is a watershed moment for Earth Observation companies, given their spatial resolution, revisit time and free availability, they offer a unique opportunity to develop satellite data services. We’re intending to use this data, are you?

Footprints in Remote Sensing

I’ve just finished my summer with Pixalytics! As I wrote a blog when I first arrived, I thought it would be nice symmetry to finish my ERASMUS+ placement with a second one.

When I started my internship, I had very little real-world experience. I was really excited and really nervous, but this internship has been a huge eye opener for me. I spent the first week understanding and reviewing the practicals within Pixalytics’ forthcoming book ‘The Practical Handbook of Remote Sensing’ to check for any errors prior to publication, which gave me a good understanding of the basics of remote sensing.

Over the next few weeks I applied my new knowledge to finding and downloading Landsat data for a commercial client. I then downloaded additional Landsat datasats and compared them to altimetry datasets to look for patterns between the two sources for the NovaSAR project. My other main job was processing Landsat 8 data to create a UK-wide vegetation mosaic. This needed cloud free images which is really difficult because the weather in UK is always cloudy, even in summer!

Plymouth is a deeply captivating city with astonishingly magnificent views and landscapes. You get the urban city, fantastic scenery and all around Plymouth are nice beaches, cities and the Dartmoor National Park which is always worth a visit. It’s a safe quiet place where everything is so close together that you can walk everywhere. The people are generally friendly and warm-hearted, and the experience of living in the Plymouth for two months has helped me to gain a more fluent level of English and a better understanding of the British culture – I now know why they constantly talk about the weather!

Overall, I’ve learnt a lot from the internship including practical skills that I will be able to carry with me to my next position. Needless to say, I will miss Pixalytics and Plymouth very dearly, and I’m thankful for the chance to work and live there. ERASMUS+ is an great opportunity that everyone should try to be part of, and I totally recommend going abroad because is an experience that stays with you to rest of your life.

Bye Plymouth, Bye Pixalytics!

Evolution of Coastal Zones

Coastal zones are the place where the sea and the land meet, and they’ve played a massive role in the life of Pixalytics. From a personal standpoint we’re based, and live, in Plymouth on the south-west coast and anyone who saw the Dawlish railway tracks swinging in midair eighteen months ago will know how these areas can affect our transport links. In addition, Sam’s PhD was focussed on the ‘Remote Sensing of Suspend Sediment in the Humber Estuary’, and so Pixalytics has effectively been grown from a coastal zone!

Last week the BBC carried a report highlighting the erosion of the Louisiana coastal wetlands; in particular, it noted that more than an area the size of a football pitch was disappearing every hour. This statistic caught our attention, and our next steps were obvious! We downloaded two images of the Lafourche Bayou in Louisiana; the first was a Landsat 5 image acquired on the 31st August 1985, and the second was a Landsat 8 image acquired twenty years later on the 02nd August 2015.

The image at the top of the blog shows the area around the Lost Lake, in the bottom left hand corner, just off the coast of Louisiana; with the 1985 image on the left, and the 2015 image on the right. The loss of land, described in the BBC report, can be seen in the northern portion of the image with a lot more water visible. However, the image on the right shows the mouth of the Atchafalya River in Louisiana; again, the 1985 image is on the left. Coastal evolution is again clearly visible, but this time there are islands that have risen from the water.

Swamplands, like in Louisiana, aren’t the only coastal zones changing. In 2011, the United Nations Environmental Programme estimated that over the last 40 years Jamaica’s Negril beaches have experienced average beach erosion of between 0.5 m and 1 m per year. Another coastal zone in decline are mangroves and wetland forests; a 2007 report noted that the areal extent of mangrove forests had declined by between 35 % and 86 % over the last quarter half century (Duke et al. 2007).

Coastal zones have social, economic and environmental importance as they attract both human settlements and economic activity; however, they are also particularly susceptible to the impacts of climate change and their evolution will have impacts on the human, flora and fauna populations of those areas. So when you’re next at the coast have a good look around; the view in front of you may never be seen again!

First Small Steps in Remote Sensing

It’s not often you get given the opportunity to travel, live in an exciting new city and get an incredible internship all in one. So when I heard about the Erasmus+ Programme I applied right away! I wanted to gain more experience in remote sensing.

When I was little I had a very big poster of the moon surface hung on my wall, it had so much detail and I would stare at it every night before I went to bed. After my parents bought my first computer, I started to search for more images of the moon and other planets and I was impressed by the complexity of what I found. This was the beginning of my fascination with remote sensing. When it came to choosing my career path, it was not hard. I knew what I wanted to become and now it sounds, and feels, right to call myself a Geomatics Engineer.

I’m currently studying two undergraduate degrees in Surveying, and Civil Engineering; but it was still hard to find an Erasmus work placement for remote sensing. I managed to find the Pixalytics Ltd with my teacher’s help, as he had previously met Dr Samantha Lavender.

After finding a place to do your internship the rest is should be easy, but not for United Kingdom. Getting my work permit from British Council was a really challenging process, and took me exactly three months. Despite doing everything right, getting responses to my emails for sponsorship was hard. It was the most awful part of the process for me, because there was nothing I could do except wait. Finally, after a lot of patience my visa arrived and I was on my way to Plymouth!

The last issue, and some people’s main concern, is getting accommodation. I did not find it hard to find a place to stay because most of the students were out of town. With a basic search on the internet I found a flat in four days, it is based a few hundred metres from the centre of Plymouth and close to the bus route to Pixalytics.

I thought I had read and traveled enough to be prepared when I stepped off the plane in London, but it was still a shock standing alone with my suitcase and hearing all the British accents around me. At first, it was difficult to adapt to the language as the accents are sometimes hard to understand. But once I’d grasped the pronunciation, I believe I’m improving every week.

Working at Pixalytics will be my first internship experience, and I am so grateful to Samantha Lavender for giving me this opportunity. Working abroad will be a memory and lesson in itself but I hope to also I hope to enhance my discipline and knowledge as well as applying my existing engineering and personal skills.

Getting my internship was a long, difficult and exhausting process, but I realized that it’s totally worth it as soon as I got to Plymouth, If anyone is thinking of applying to the Erasmus+ programme, I would totally recommend it!
