Title: Carbon and nutrient transports in the subtropics
Speaker: Elaine McDonagh (NORCE, Norway)

Elaine McDonagh is a Research Professor at the Norwegian Research Institute, NORCE, and part of the Bjerknes Centre for Climate Research in Bergen, Norway. Prior to moving to Bergen in 2019 she was in the Marine Physics and Climate Group at the National Oceanography Centre, UK, for 19 years, where she continues to have a position.  Her undergraduate degree in Environmental Sciences and PhD were completed at the University of East Anglia. Her research interests are in the oceans´ role in climate, particularly how the ocean takes up heat, freshwater and carbon and the interaction with ocean circulation and water masses. She coordinates the Horizons Europe project EuroGO-SHIP and co-chairs the International GO-SHIP programme that makes the observations on which her research is based.


Title: Comparing Simulated and Observed AMOC Transport Estimates
Speaker: Gokhan Danabasoglu (NCAR, USA) 

Gokhan Danabasoglu is a Senior Scientist and the Chief Scientist for the Community Earth System Model (CESM) at the National Center for Atmospheric Research. His research interests include understanding the role of the oceans in the Earth’s climate system; computational modeling of the oceans; and investigations of mechanisms, prediction, and impacts of inter-annual to decadal time scale Earth system / climate variability, particularly associated with the North Atlantic and the Atlantic meridional overturning circulation (AMOC).

Title: Freshwater and AMOC in the North Atlantic Subpolar Gyre

Speaker: Fiamma Straneo (Scripps Institution of Oceanograph, USA)



Fiamma Straneo is a Professor and the co-Director of the Polar Center at the Scripps Institution of Oceanography of the University of California San Diego. Prior to this position, she was a scientist at the Woods Hole Oceanographic Institution from 2000 to 2017. Her research focuses on the high latitude North Atlantic and Arctic Oceans, their interaction with the atmosphere, sea-ice and the Greenland Ice Sheet, and the Atlantic Meridional Overturning Circulation. Much of her work involves interpreting data from the high latitudes collected using platforms such as icebreakers, fishing vessels, helicopters, snowmobiles and autonomous surface and underwater vehicles. Straneo has led over 20 field expeditions to the Arctic and Greenland. She co-chaired the Climate and Cryosphere Program of the World Climate Research Program from 2018-2022 and is a co-chair and founder of the Greenland Ice Sheet/Ocean Science Network (GRISO).


Title: Simulation-based approaches for quantitative observing system design
Speaker: Patrick Heimbach (University of Texas at Austin, USA)

Patrick Heimbach is a computational oceanographer, professor in the Jackson School of Geosciences, and W. A. “Tex” Moncrief, Jr., chair III in Simulation-Based Engineering and Sciences in the Oden Institute at the University of Texas at Austin. His research focuses on ocean and ice dynamics and their role in the global climate system. He is an expert on the use of inverse methods and automatic differentiation applied to ocean and sea ice model parameter and state estimation, uncertainty quantification and observing system design. Patrick earned his Ph.D. from the Max-Planck-Institute for Meteorology and the University of Hamburg, Germany. Prior to joining UT, he spent 16 years at MIT. Among his past and present professional services are memberships on the US National Academy of Sciences’ Ocean Studies Board, NSF’s Advisory Committee for Cyberinfrastructure, the CLIVAR/CliC Northern Ocean Regional Panel, the US CLIVAR Ocean Uncertainty Quantification working group, and the UN Ocean Decade’s Deep Ocean Observing Strategy (DOOS) programme.

Title: Observing the South Atlantic Meridional overturning circulation at 34.5S
Speaker: Renellys Perez (NOAA, USA)

Renellys Perez is an oceanographer at NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML), and is the Deputy Director of the Physical Oceanography Division. Her research is focused on tropical Atlantic variability and the processes that influence sea surface temperature and ocean current variability in the Atlantic, and characterizing the variability of the boundary currents and the overturning circulation in the South Atlantic and their influence on weather, climate, and sea level. She is the lead investigator of the Southwest Atlantic Meridional overturning circulation (SAM) and the Tropical Atlantic Current Observations Study (TACOS), and is the co-lead investigator of the PIRATA Northeast Extension (PNE) project. Through her collaborations with NOAA and national and international scientists, she understands the importance of developing an all-Atlantic observing strategy to tackle important problems like the Atlantic overturning circulation. She has participated in various national and international panels including the US CLIVAR Phenomena, Observations, and Synthesis panel (member 2014-2015, co-chair 2015-2017), US AMOC Task Team 1 (vice-chair 2014, chair 2015), SAMOC Executive Committee (member 2020-present), AtlantOS Steering Committee (2021-present), and the PIRATA Scientific Steering Group (2022-present). She received a Ph.D. in oceanography from Oregon State University in 2006, and was a National Research Council research associate from 2006-2008. She is passionate about building a more diverse and inclusive science community through mentorship and outreach.


Title: GOHSnap: Updates from the field 
Speaker: Jaime Palter (University of Rhode Island, USA)

Jaime Palter is an associate professor of oceanography at the University of Rhode Island. She studies ocean circulation and biogeochemistry, focusing on the transport of heat, carbon, and oxygen through the ocean and across the air-sea interface. To do this, she collects new observations with moored and autonomous platforms, including Saildrones and Seagliders, and combines them with thee vast archives of historical hydrographic and satellite data. She leads the Gases in the Horizontal and Overturning circulation of the Subpolar North Atlantic (GOHSNAP), which added oxygen and pCO2 sensors to the OSNAP moorings in the Labrador Sea.

Title: Observations of the boundary currents and AMOC at 11°S - the TRACOS array
Speaker: Rebecca Hummels (GEOMAR, Germany)

Dr. Rebecca Hummels is a seagoing physical oceanographer working at GEOMAR in the research division Ocean Circulation and Climate Dynamics. 
Her research focus is on observations of oceanic/climate variability in the tropical Atlantic ocean on large and small scales including
     ⇒  Strength and Variability of the (South Atlantic) MOC
     ⇒  Western Boundary Circulation Systems
     ⇒  diapynal mixing processes and their influence on the heat budget of the surface mixed layer

The upper-ocean circulation of the tropical Atlantic is a complex superposition of thermohaline and wind-driven flow components. This means that the northward AMOC branch in the tropics is e.g. superimposed by the shallower overturning associated with the wind-driven Subtropical cells, which connect the subduction sites of the subtropics with climate-relevant eastern equatorial upwelling regions. The TRACOS array aims at observing most of the TRopical Atlantic Circulation & Overturning at 11°S. At the western boundary five tall moorings were deployed off Brazil between 2000 and 2004 to monitor the variability of the strong western boundary current (WBC) system - more specifically, the North Brazil Undercurrent (NBUC) and the Deep Western Boundary Current (DWBC). Due to the success of this array, a similar mooring constellation has been installed off Brazil since July 2013 until now. In addition to the moorings, numerous ship-sections along 5°S and 11°S are accomplished. At the eastern side the Angola current is observed since 2013 with 1-2 moorings. Simultaneously to the boundary observing systems, the observational program at 11°S was extended in 2013 to observe the basin wide circulation: Bottom pressure sensors (BPRs) were deployed on both sides of the basin. The BPRs and all ship surveys are used to estimate AMOC variability at 11°S on seasonal to interannual time scales. Especially, in combination with other AMOC arrays or embedded in the TAOS or PIRATA programs, this array has great potential for understanding mechanisms relevant for tropical Atlantic variability, as well as meridional coherence and long-term changes of AMOC variability.
