1 DFO Northwest Atlantic Ocean Monitoring & Mooring Programs OSNAP Planning Meeting 26-27 April 2011 BIO

2 Atlantic Zone Monitoring Program (AZMP) Focuses on physics, chemistry and lower trophic-level biology on the continental shelf and upper slope. Data collected since 1998 Cooperative effort of DFO Gulf, Maritimes, Newfoundland & Labrador, and Quebec regions, with Integrated Science Data Management (HQ) Objectives: – Characterize and understand the causes of ocean variability at seasonal and interannual scales. – Provide adequate data to support sound development of ocean activities. – Provide historical databases to address future issues.

3 AZMP – Composite Climate Index

4 Bottom Temperature Strongly Related to NAO (Petrie, 2007) Negative NAO → warmer than normal bottom temperatures over the Labrador-Newfoundland Shelf, the Gulf of St. Lawrence and the eastern Scotian Shelf; and colder than normal conditions over the central and western Scotian Shelf and Gulf of Maine. The pattern is reversed under positive NAO forcing. Temperature Anomaly Impact on Continental Shelf

5 AZOMP – Labrador Sea Labrador Sea (AR7W) and Extended Halifax Section (XHL) Monitoring Program - One cruise per year in the May/June period - PO component focuses on interannual variability in water mass properties and circulation including DWBC, and related atmospheric and ice conditions. - CO component focuses on nutrients, the carbon cycle, carbon dioxide storage, and chemical tracers which indicate circulation patterns and rates. - BO component focuses on lower-trophic-level (bacteria, phytoplankton, zooplankton) biomass, productivity and biogenic carbon inventories (particulate and dissolved organic carbon).

6 AZOMP – Argo & Complementary Data Argo Float Program - Used to complement observations from AR7W and XHL - BIO is one of the DFO oceanographic labs which contribute to the International Argo Program. - T & S profiles are used in developing AZOMP indices and products. Complementary Observations - Remote sensing SST and color through AZMP - Met. and sea ice observations - Slope and deep water obs from AZMP - Monitoring of flows through Canadian Archipelago and Davis Strait Argo float locations as of 16 Feb 2010

7 Moored Current/Hydrographic Measurements Issues: Arctic outflows (with UW) Labrador Current & other slope currents/hydrographic variability Currents variability for oil & gas issues Deep flows connecting to AMOC Locations since 2000 (at present): Davis Strait (w UW) Davis Strait (w UW) Labrador Shelf & Slope Labrador Shelf & Slope Orphan Basin & Knoll Orphan Basin & Knoll Flemish Pass Flemish Pass Laurentian Channel & Fan Laurentian Channel & Fan Scotian Slope (w & w/o UK RAPID) Scotian Slope (w & w/o UK RAPID)

8 Near-Bottom Currents

9 Summary Well-established monitoring programs provide a strong basis of collaboration with OSNAP. Monitoring and enhanced understanding (e.g. ecosystems) of the Labrador and Newfoundland shelves is a high priority for DFO. Moored activity is declining with DFO due to changes in funding availability.

11 Halifax Marine Research Institute HMRI is a newly-established entity to foster collaboration between Dalhousie University and other local universities with federal government labs Doug Wallace (CERC Chair) – executive director

12 Doug Wallace – Research Interests Central Labrador Sea Biogeochemical Mooring with SeaCycler. This could be a contribution to OceanSITES and a nascent sub-program called MOIN Possibly a Halifax-Kiel cooperative effort.

13 Needs:

14 Doug Wallace – Research Interests Central Labrador Sea Biogeochemical Mooring with SeaCycler. This could be a contribution to OceanSITES and a nascent sub-program called MOIN Possibly a Halifax-Kiel cooperative effort. Orphan Basin Observatory with interest in air-sea heat and CO2 flux, deep circulation and Lab Sea outflow.

15 Climatological Mean Air-Sea CO 2 Flux (Takahashi et al, 2009)

16 Doug Wallace – Research Interests Central Labrador Sea Biogeochemical Mooring with SeaCycler. This could be a contribution to OceanSITES and a nascent sub-program called MOIN Possibly a Halifax-Kiel cooperative effort. Orphan Basin Observatory with interest in air-sea heat and CO2 flux, deep circulation and Lab Sea outflow. Surface pCO2 sampling in the region wherever possible.

17 ICOS-OCEAN: North Atlantic Observing System (with future Canadian involvement?) Ocean Observatory Instrumented shipping route Hausgarten Cape Verde

18 Doug Wallace – Research Interests Central Labrador Sea Biogeochemical Mooring with SeaCycler. This could be a contribution to OceanSITES and a nascent sub-program called MOIN Possibly a Halifax-Kiel cooperative effort. Orphan Basin Observatory with interest in air-sea heat and CO2 flux, deep circulation and Lab Sea outflow. Surface pCO2 sampling in the region wherever possible. Possible sub-surface tracer release experiment somewhere along the western Lab Sea or Newfoundland slope. Kiel group and Jim Ledwell (WHOI) have both expressed interest. General hydrographic work in the region in close collaboration with Kumiko on freshwater tracers, CO2, etc…
