P16 - Canada-Newfoundland Operational Ocean Forecasting System (C-NOOFS)

The Canada-Newfoundland Operational Ocean Forecasting System (C-NOOFS) is currently the most advance initiative within Canada in terms of downscaling GODAE products. The goal is to foster an end-to-end operational ocean prediction system for the North West Atlantic with particular emphasis on Canadian Waters. This project includes

1. Automated collection of in situ and remotely sensed data e.g. temperature, salinity, oxygen, nutrients and chlorophyll profiles
2. Development of new, near real-time data streams from marine mammals (seals) and Fisheries and Oceans research and monitoring cruises
3. Sharing of these new data sets with data service centres
4. Assimilation of data in ocean models
5. Transmission of model forecast output to defined government end-users (e.g. the Canadian Coast Guard) and generation of publicly available ocean model output via a web page

The planned system will feature two coupled grids:

• A ¼ degree grid covering the Northwest Atlantic. It is a subset of the ORCA025 (1/4 deg) global model domain which has poles situated over Canada, Russia and Antarctica. The C-NOOFS initiative is restricted to the north-west Atlantic (35N-80N, 77W-35W) and has a horizontal resolution of roughly 20 km in the south of the domain and 6 km at the northern extremities in the Canadian Arctic Archipelago. The open boundary conditions are presently supplied by the Mercator ocean product PSY1v2 for the North Atlantic.
• A refined grid nested within the Northwest Atlantic model that covers the shelf regions around Newfoundland. The grids will be two-way coupled using the AGRIF nesting protocol with a grid refinement factor of 3.

Outcomes
Anticipated outcomes from C-NOOFS for this upcoming year include daily updates for the Northwest Atlantic domain with wind forecasts provided by Environment Canada. No data assimilation is planned in the first set of model products which will include

1. data extracted along transects of regular DFO monitoring cruises (3 times a year)
2. vertical profiles coinciding with available observed in-situ profiles (e.g. from Argo floats, seals)
3. standard MERSEA metrics. In the future, an increase in resolution from ¼ degree North West Atlantic will be considered once the system is operational.
