Single Species Assessments

Change in Production Potential

Annual daily mean chlorophyll a concentration (orange) and primary production (green) for the Northeast Shelf Large Marine Ecosystem.

Surface chlorophyll a concentration (top) and chlorophyll anomaly (bottom) for the Northeast Shelf Large Marine Ecosystem.

Change in Climate Conditions

Northwards shift of red hake Urophycischuss based in bottom trawl survey data, cool to warm, blue to red, shades scale from low to high abundance (extracted from Nye et al. 2009).

Time series of sea surface temperatures in eco-regions of the Northeast Shelf Large Marine Ecosystem with projected temperature based on an ensemble of climate projection models.

Application of Ocean Observing Data

in an Ecosystem Context

Indicators in status assessments and response analyses-Advisories, Status Reports, Integrated Ecosystem Assessments

Model parameterization-Fisheries Ecosystem Management Plans

Spatial analyses-consultation with entities dealing with marine spatial planning issues

Definition of habitat

Production level forcing of higher trophic level yield

Climate projections-expectations of change in species distributional range and fisheries availability

Continuing and New Observing Data

of Interest for Ecosystem Research

Indicators that are responsive to ecosystem change

Measurements that help us understand primary production and the foodweb dynamics that control energy flow in the ecosystem—resulting in harvestable seafood

Variables that are part of our modeling systems for eco-production units

Parameters that control the behavior of organisms and thus define their habitats

Observing system measurements that can be contextualized to climate change projections

Highlighted Practical Issues

Data assimilative hindcastsof circulation-with community available outputs of temperature, salinity, density and flow

Multiple monthly glider sections to estimate transport

Continued real-time analyses of habitat definition

Better coordination with NERACOOS
