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

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)

Fulfilling marine potential

Next generation opportunities

require next generation thinking

Specialists feed into big picture

from articulators to decision

makers – new gen. scientists

‘Sea literacy’ must extend

through all facets of society

The next 20 years…
