Interview with Nicolas Longépé - How satellite imagery can support the aquaculture sector

Nicolas Longépé is currently a Research Engineer in the Radar Application Division of Collecte Localisation Satellites (CLS), Plouzané, France. He has worked with CLS since 2010. From 2007 to 2010, he was with the Earth Observation Research Center of the Japan Aerospace Exploration Agency (JAXA) in Tokyo, Japan, for 11 months as a Japan Society for the Promotion of Science Fellow, and then as an Invited Researcher. His research interests include space-borne remote sensing applied to maritime security (oil spill, sea ice, iceberg, and ship detection/tracking) and to environmental and natural resource management.

Ocean acidification harms organisms whose life depends on shells and on coral reefs. The shell-building capacity of this organism declines with decreasing aragonite saturation, which is due to the increase of average pH in the seas. Therefore, it affects important marine ecosystems hosting high biodiversity and food availability[1].

BlueBRIDGE interviews Professor Yannis Vassiliou, Director of Institute of Computer and Communication Systems & Professor at the National Technical University of Athens

Recently BlueBRIDGE had the opportunity to spend some time with Yannis Vassilou, Director of Institute of Computer and Communication Systems & Professor at the National Technical University of Athens to discuss all things Virtual Research Environments (VREs). Professor Vassiliou discussed the use of VREs in the education sector providing BlueBRIDGE with some first-hand insights into their use and their potential...

Bringing food web models to the next level: Interview with Jeroen Steenbeek, Head Technical Committee @ Ecopath Research and Development Consortium

Jeroen Steenbeek, Head Technical Committee at Ecopath Research and Development Consortium, explains why the food web models are fundamental for predicting the human impact on marine ecosystems and the work he is planning to do with BlueBRIDGE to bring the Ecopath with Ecosim approach at a next level.

Estimating length-weight relationship for marine species

The size of a fish is usually measured using its body length. However, regulating fishing activity to prevent overfishing and stocks depletion also requires body weight estimate. In particular, weight is often important to estimate average stock biomass.  Average length information is available for many stocks; because of this, estimating weight from length can be crucial for fisheries management. Species weight is correlated to length by means of parameters related to the species growth rate and its shape. A recent work by Froese et al.
