Coastal Ocean and Shelf Seas (COSS-TT)
Starting in the mid-2000s, GODAE (Global Ocean Data Assimilation Experiment) fully embraced the importance of coastal ocean “intermediate users” of ocean forecasting products for coastal applications. To address this need, the Coastal and Shelf Seas Working Group (CSSWG, 2006-2008) was established with the mission to bridge global and coastal prediction strategies by quantifying elements that demonstrate the value of GODAE results for regional, coastal and shelf seas models, and forecasting systems. With the evolution of the initial GODAE phase to GODAE OceanView (GOV) in 2008, the CSSWG evolved into the Coastal Ocean and Shelf Seas Task Team. The COSS-TT is now one of the OceanPredict Task Teams.
Terms of Reference:
“The main goal and central mission of the COSS-TT is to work within OceanPredict towards the provision of a sound scientific and expert basis for sustainable multidisciplinary downscaling and forecasting activities in the world’s regional and coastal oceans. The strategic goal of the COSS-TT is to help achieve a truly seamless framework from the global to the coastal/littoral scale. A major contribution is to address the particular challenges on monitoring and forecasting in coastal areas and regional seas, where the majority of human marine activities take place. As these are also the areas of enhanced exploitation of marine resources, the COSS-TT has a mission well aligned with society’s needs and benefits.”
The main disciplines considered within the TT are coastal ocean physics and interactions between physical and biogeochemical processes, but the TT has close ties with other OceanPredict Task Teams, and holds some of its meetings together with them.
The COSS-TT is an international team, with members from every continent. It has through the years consolidated a broader coastal scientific community involved in developing and advancing methodologies supporting Coastal Ocean Forecasting Systems (COFS). The COSS-TT and its community meet approximately every 18 months. Meetings aim to bridge several communities and subcultures by addressing their specific questions together, as reflected by the target attendees
- Global/regional ocean forecasters, in particular those already present in OceanPredict (e.g. on large-scale model assessment and improvement in coastal regions)
- Coastal modellers, experts and scientists (our “core” community)
- Experts in international ocean observing programs with a coastal component (e.g. on synergistic studies with coastal modellers and added value).
The COSS-TT is led by the co-chairs:
The COSS-TT aims to advance science and expertise in coastal regions in support of two categories of ocean forecasting systems. First of all, obviously and centrally, the TT address Regional/Coastal Ocean Forecasting Systems (R/COFS), at several stages of development (scientific concept, pre-operational, operational). However the TT also addresses the scientific and expert needs of Large-scale Ocean Forecasting Systems (LOFS), as long as they have stakes in coastal regions and shelf seas and/or as they aim to provide initial/boundary conditions for coastal models as part of downscaling or upscaling services.
Six international coordination meetings (2012-2018) have helped define broad priority topics where science and expertise are needed for those systems:
- Monitoring of physical and biogeochemical parameters in coastal regions (in particular permanent/long-term), including linking with the active regional/coastal altimetry community and discussing how altimetry can improve the forecast quality and enable new applications in the regional/coastal oceans
- Development of fine-scale coastal ocean models
- Model-observations synergy in the coastal ocean:
- Using observations to guide coastal model development and assessment
- Using models to connect and interpret sparse coastal observations
- Using coastal models to synthesize observations (data assimilation, machine learning)
- Using models to design and optimize coastal observing systems (OSE, OSSE, array design)
- Downscaling the ocean estimation problem from large-scale to coastal-scale models, data and forcings,
- Coastal-scale atmosphere-waves-ocean couplings
- Ecosystem response to the physical drivers
- Risk assessment in the coastal ocean, including probabilistic and AI approaches, e.g. regarding extreme events.
The Task Team will continue to address these topics at future meetings, through special Activities, and in collaboration with other Task Teams.
Some COSS-TT activities are listed below:
- Six task team meetings have been organized between 2012-2018 to share science and good practices, promote international networking and advance strategic planning.
- A Coastal System Information Table has been compiled.
- Six special sessions have been sponsored by the Task Team at AGU/Ocean Sciences Meetings (2008-2018); these have consolidated the outcomes of the TT workshops and allowed outreach to the broader scientific community. Most recent session: AGU-OSM / Portland, OR, USA / Feb 2018.
- Two synthetic COSS Community papers from the 2013 Symposium have been published in Journal of Operational Oceanography.
- We initiated the ARCOM initiative (Altimetry for Regional and Coastal Models) as a common activity between the TT and the CAW (Coastal Altimetry Workshop, http://www.coastalaltimetry.org , P. Cipollini). ARCOM co-chairs: C. Dufau (CLS) and J. Wilkin (Rutgers U.).
- COSS-TT members contributed to the 25th Altimetry workshop in Azores (Oct. 2018): http://www.altimetry2018.org
- COSS-TT co-chairs first-authored or co-authored several OceanObs (Honolulu, Sept. 2019) papers (De Mey-Frémaux et al., 2019; Davidson et al., 2019; Ponte et al., 2019)
- We initiated an activity with the IV-TT: Class 4-based intercomparison of LOFS and R/COFS.
- COSS-TT co-chairs are also members of the DA-TT and OSEval-TT.
- The first COSS Topical Collection of 15 papers has been published in Ocean Dynamics, with presentations from TT meetings. The second COSS Topical Collection is in progress.
- Co-chair V. Kourafalou is a Member of JCOMM’s Inter-programme Expert Team on “Integrated Marine Meteorological and Oceanographic Services within WMO and IOC Information Systems” (IPET-MOIS); co-chaired by Eugene Burger (NOAA, USA) and Youlong Liu (NMDIS, China).
- Both COSS-TT co-chairs are members of the org Steering Committee (an initiative proposed within the framework of the United Nations Decade of Ocean Science).

The COSS-TT co-chairs are strongly involved in CoastPredict, a UN Decade programme proposed by the international coastal community as a contribution to ‘the science we need for the ocean we want’.

The regional and coastal ocean, as a complex interface area where land, hydrology, atmosphere, and ocean interact, concentrates a wide range of actors dealing with increasing socioeconomic and environmental issues. Forecasting the coastal ocean remains a key challenge, also in view of climate change impacts.
