Marine Ecosystem Analysis and Prediction (MEAP-TT)

Introduction

The MEAP Task Team is focused on developing the underpinning science and tools that will further the integration of biogeochemical and ecosystem models into existing ocean operational systems. The Task Team’s mission is to advocate for an expansion of the ocean observing system with respect to biogeochemical and biological properties, to support method development for the assimilation and modelling of Essential Biogeochemical Variables (EBV), to exchange of scientific advances and transfer of capabilities between academic and operational centers of expertise, and to help bridge the gap with end-users.

The area of biogeochemical and ecosystem prediction is of significant societal relevance, supports the UN Sustainable Development Goals 13 (climate change) and 14 (life below water), and supports Blue Growth. It is an area likely to make important advances in the next 5 to 10 years because relevant ocean observing capabilities are rapidly expanding.<

The MEAP-TT is led by the co-chairs:

Objectives

  • Drive forward method development focused on two main aspects:
    • the extraction of ecological information from proxy observations (incl. satellite observations of ocean colour and bio-optical measurements from autonomous in-situ sensors), and
    • the development of strongly coupled assimilation of biological and physical observations into ocean models;
  • Advocate for the expansion of global ocean observing capabilities with respect to biogeochemical and biological variables (e.g. via BGC Argo), and guide optimal design including through observing system simulation studies;
  • Contribute to the development and provision of biogeochemical and biological products for end users through assessments of product quality and end user needs;
  • Demonstrate and quantify the improvements in biogeochemical and biological model skill resulting from advances in biogeochemical/biological ocean observation and assimilation, including identification of metrics for system evaluation.

Activities

The MEAP-TT will promote scientific collaboration and deliver joint outputs of team members by:

  • Meeting in periodic video conferences (every three months)
  • Meeting annually in person at Task Team workshops
  • Convening MEAP theme sessions at international conferences (e.g. EGU, Ocean Sciences, AMEMR)
  • Editing special issues in Journals (e.g. Special Issue on Biogeochemical-Argo modelling in Biogeosciences)
  • Co-authorship of horizon publications and influential reports (e.g. Fennel et al., 2019; ETOOFS manual, Ocean State Reports)
  • Engagement of ecosystem analysis and prediction stakeholders (e.g. IMBER, OceanSITES, BGC-Argo)

Workshops and meetings

An important  activity of the MEAP-TT is to organise regular workshops. In order to increase collaboration, these workshops are often held jointly with other TTs or groups. Planned and previous workshops include:

 

→ Joint DA/MEAP-TT workshop 2016, Santa Cruz, USA

→ MEAP-TT Workshop 2015, Halifax, Canada

→ MEAP-TT Workshop 2012, Exeter, UK

 

 

Online meetings

Since Oct 2020 the MEAP-TT started holding regular virtual Task Team meetings to discuss TT activities and future plans.

TT quad-chart

The task team quad-chart provides a quick glance at the TT’s activities, achievements and future plans.

 

Marine Ecosystem Analysis and Prediction Task Team (MEAP-TT) – June 2018
Short description and objectives of the activities started/planned for this year:
Accomplishments of the TT this year:
Main activities:

• Main objective: evaluate of downscaling from global to regional physical/biogeochemical configurations across GODAE/GOV systems.

Year 3 milestone: organizing of a session on down-scaling as a multi-TT event: “Ecosystem response to physical drivers in coastal regions”, (cross-cutting theme at the 6th International meeting of COSS-TT, Madrid 19-21 September 2018)

Main achievements:

• Special session at 2018 Ocean Sciences Meeting (OSM) “Development and Advances of Modeling and Forecasting Marine Biogeochemistry and Ecosystems” (convenors: F. Chai, P. Xiu, M. Gehlen, S. A. Siedlecki)

• Informal TT meeting at OSM

• Special session at 2017 EGU GA “Recent advances in analysis and prediction of marine biogeochemistry and ecosystems” (convenors: Gehlen, Fennel, Dutkiewicz (IOCCG))

• TT meeting at 2017 EGU GA

Future plans to continue/ improve current activities:
Issues/ problems:
Main future plans:

• On-going: review of impacts of DA methods on biological/biogeochemical model

• Preparation of scientific session at international GODAE OceanView Symposium in 2019

Main issues:

• Difficulty to ensure a good representation of non-European members at meetings organised in Europe due to travel restrictions

• Difficulty to carry out concrete actions (e.g. intercomparison projects) on best effort basis (enthusiasm during planning dies off rapidly as it implies extra work added to an in general already heavy load)
