Biography

Carlos Moffat received a B.S. in Marine Biology from the University of Concepción, Chile, and a Ph.D. in Physical Oceanography from the MIT-WHOI Joint Program. He was a Postdoctoral Researcher at the Woods Hole Oceanographic Institution. Since early 2016, he has held a faculty position at the School of Marine Science and Policy at the University of Delaware.

His research interests span a range of problems in Coastal Physical Oceanography with a focus on polar regions. These include understanding the role the ocean plays in glacier retreat, the impact of increased melting from Antarctica on the Southern Ocean, and how polar ecosystems are responding to climate change

Scientists could soon lose a key tool for studying Antarctica's melting ice sheets as climate risks grow

NBC News  online

“It’s not a faucet of water you can turn on or off,” said Carlos Moffat, associate professor of marine science and policy. “Are we really going to depend on other countries to collect the observations we need to know how sea level is changing in the United States?”

If there was a toolbox for understanding Antarctica, an icebreaker like the Palmer is “the hammer,” says Carlos Moffat, professor of marine science and policy. “You need it to get so much done.”

Global Drivers on Southern Ocean Ecosystems: Changing Physical Environments and Anthropogenic Pressures in an Earth System

Frontiers

Morley, S.A., Abele, D., Barnes, D.K.A., Cárdenas, C.A., Cotté, C., Gutt, J., Henley, S.F., Höfer, J., Hughes, K.A., Martin, S.M., Moffat, C., Raphael, M., Stammerjohn, S.E., Suckling, C.C., Tulloch, V.J.D., Waller, C.L., Constable, A.J.

The manuscript examines the present and future global drivers of Southern Ocean (SO) ecosystems. Notably, atmospheric ozone depletion over Antarctica, beginning in the 1970s, has been a crucial factor, leading to stratospheric cooling and a stronger polar vortex, which in turn increases the occurrence of the Southern Annular Mode's positive phases (SAM). This results in warm air moving over the Western Antarctic Peninsula and cold air over the West Pacific sector. SAM and El Niño events also influence the Amundsen Sea Low, causing sea ice anomalies in the Pacific sectors. Strengthened westerly winds are associated with the upwelling of warmer water onto continental shelves, particularly in the East Pacific and Atlantic sectors. Melting glaciers and ice sheets have created ice-free areas that may enhance iron availability, potentially overcoming a limiting factor for primary production in much of the SO. Increasing CO2 is a significant anthropogenic driver with future effects on marine ecosystems, and the presence of persistent organic pollutants (POPs) and plastics is growing in the SO due to increased marine traffic and weaker ocean barriers. While the ongoing recovery of the ozone hole adds uncertainty to sea ice trends, the manuscript highlights the certain impacts of the current rate of change in physical and anthropogenic drivers on the Marine Ecosystem Assessment of the Southern Ocean (MEASO) in the near future, affecting a wide range of marine ecosystem aspects.

The West Antarctic Peninsula (WAP) region has experienced significant temperature and sea ice dynamics changes since the mid-twentieth century, impacting the local ecosystem, ocean chemistry, and hydrographic conditions. Although changes in these trends have been observed in the 21st century, their effects on ocean physics, chemistry, and the high-productivity shelf ecosystem are not fully understood. The WAP shelf is crucial for krill stocks and higher trophic levels, making it a valuable model for studying how climate and sea ice variations may affect high-latitude ecosystems. Despite being one of the best-studied shelf regions in Antarctica, there are still gaps in spatial and temporal data needed to comprehend the complex system's dynamics and evolution. The summary outlines the current state of knowledge, identifies cross-disciplinary research priorities, and underscores the importance of defining the causes, extent, and timing of variability and change throughout the system. A coordinated observing system is necessary to monitor and understand these changes in the future.

Variability and Dynamics of Along‐Shore Exchange on the West Antarctic Peninsula (WAP) Continental Shelf

JGR Oceans

Wang, X., Moffat, C., Dinniman, M.S., Klinck, J.M., Sutherland, D., Aguiar‐González, B.

2023-11-08

The continental shelf of the West Antarctic Peninsula (WAP) exhibits significant variations in water properties due to the influence of the warm Bellingshausen Sea in the south and the cold Weddell Sea water in the north, flowing through Bransfield Strait. These variations impact glacier retreat and other environmental factors, but their dynamics are not well understood. A study using a high-resolution numerical model and hydrographic data from Palmer Deep investigates the seasonal and interannual changes in along-shore transport. It reveals a seasonal pattern of water movement, with cold water moving towards the central WAP in winter and warmer water flowing towards Bransfield Strait in summer. The strength and direction of this flow are influenced by the Southern Annual Mode (SAM) and wind patterns, leading to variations in water temperature along the WAP continental shelf. This study underscores the importance of along-shore exchange in shaping the hydrographic conditions in the region.
