3 Different
Roles:o Data scientist at Cefas
• Finding NEAM-EO
o Marine Lead Defra EOCoE
• Bridges to Satellites
o Marine Liaison UK-GEOS
• From land use change to river
runoff to marine animal health
“Satellite Science”?• From LE orbit, satellite Remote Sensors (RS)
detect EM energy reflected from earth
• Information on objects/areas from a distance
• “Earth Observation”
(EO)
All* of the EO/RS Satellites
NASA and ESA MS imagery for Land
NASA and ESA MS for Ocean Colour
NASA Infrared and Microwave
ESA Synthetic Aperture Radar
NASA Radar Altimetry
NASA Radar Scatterometry
NASA Microwave Gravity
Commercial Sat-AIS receivers
In situ data collection is vital
Satellites only measure the surface
Interference from dust, cloud, glint, fog, smoke
Reduced accuracy in ‘complex’ waters
including coastal areas & high latitudes (polar)
Satellites revisit every day / every few days
Improved algorithms are enhancing accuracy
in problematic areas
Cloud still an issue but we have radar + LiDAR
plus spatial resolution is improving
Limitations of Remote Sensing

Finding NEAM-EOTracking North-East Atlantic Mackerel with EO data
Biermann, L., Couce, E. and Van Der Kooij, J.
NEAM in the North Sea
Mackerel distributions
from acoustic data were
related to bathymetry
and EO-derived:
1. Sea temperature
range of 13-15ºC
2. [Chlorophyll-a]
3. Euphotic zone depth
4. Mean Sea Level
Anomalies

NEAM in the North-East Atlantic
Where ships slowed down to trawl,
mackerel had been present in
space and time.
No survey data over winter (Q1), so we got a little creative!
Based on how elephant seals forage in the
Antarctic, we tested satellite AIS data from
fishing boats to detect areas of ‘foraging’
(trawling) based on travel speeds.

Earth Observation Centre of
Excellence (Defra EOCoE)
Cefas leads the Marine portfolio
Joined up to make EO accessible for monitoring
through the CoE EO Collaborative Platform
Vision:Centralised and bespoke
‘one-stop’ EO portal for
UK government agencies
What it means to me:Help make satellite data
easier to use…
Barriers to uptake in GOV?
1. Satellite data are cumbersome to use, requiring
specialist knowledge and/or software
2. Lack of information on the (vast) range of existing
satellite products, as well as their potential
applications (and limitations)

Next generation opportunities
require next generation thinking
Specialists feed into big picture
from articulators to decision
makers – new gen. scientists
‘Sea literacy’ must extend
