The Ocean Decade: A True Ecosystem Modeling Challenge

Our manuscript about modelling challenges for the Ocean Decade is out

We invite you to see our latest contribution in Frontiers of Marine Science. Here, we challenge the marine ecosystem modeling community to address how to: (i) enable ocean managers and decision-makers to use their science, (ii) communicate their science, and most importantly (iii) ensure co-design of their science to achieve sustainable development. For this, we define ecosystem models as those that span physical and human drivers of change in the full ecosystem from plankton to top predators.

December 2019 – Course “spatial-temporal data framework”

Jeroen Steenbeek — Mon, 09 Dec 2019 07:22:07 +0000

9 December 2019 – FWRI, St. Petersburg, FL., USA – Jeroen Steenbeek, Joe Buszowski.

In this advanced workshop, students explored the workings of the Ecopath with Ecosim spatial-temporal data framework and its utility to Ecospace. Students interacted with a stripped-down version of the data framework to connect a case study model with time-varying driver data. Students discussed the process of preparing geo-spatial data needs for the different Ecospace map layers, and best practices in sharing spatial-temporal data with others.

The spatial-temporal data framework is a GIS data exchange toolkit for EwE, available via a professional license.

Even in light of the multiple perturbations experienced in this region, fish and shellfish landings have remained stable or increasing. These disturbances have resulted in many unforeseen ecological consequences; one such consequence is the loss of marsh vegetation in southern Louisiana (LA). Marsh habitats are thought to function as nursery habitats for post-larval and juvenile fishes, providing both refuge from predation and increased foraging opportunities. As the loss of marsh appeared to have a null effect on fish and shellfish yields, there evolved a hypothesis that described a positive effect on nekton production; increasing marsh edge distance during marsh degradation provides a potential short-term increase in marsh access for organisms. Here we used Geographic Information System (GIS) data to determine the patterns of marsh loss over a 10 year period and to create marsh edge maps for further analysis in an ecosystem model. We used the ecosystem model Ecopath with Ecosim and Ecospace (EwE) to determine if a suitable response mechanism between estuarine organisms and marsh edge distance could be developed. The scenario analysis of multiple theoretical response functions showed Ecospace's ability to model changing habitat and environmental variables over time and space. More specifically, while the results of this modeling effort revealed species-specific responses to marsh edge, the association between nekton and marsh edge may not be as tightly coupled as once thought in coastal LA.},
