LTER Palmer, Antarctica (PAL): Land-Shelf-Ocean Connectivity, Ecosystem Resilience and Transformation in a Sea-Ice Influenced Pelagic Ecosystem - continuingSince 1990, Palmer LTER (PAL) research has been guided by the hypothesis that variability in the polar marine ecosystem is mechanistically coupled to changes in the annual advance, retreat and spatial extent of sea ice. Since that time, the hypothesis has been modified to incorporate climate migration, i.e. the displacement of a cold, dry polar climate by a warm, moist climate regime in the northe

Wave Glider Observations of Surface Fluxes and Mixed-layer Processes in the Southern OceanAir-sea interaction in the Southern Ocean connects the "conveyor belt" overturning circulations in each the major oceans of the world (Atlantic, Pacific, and Indian), providing the long-term memory of the climate system by determining the rates of oceanic heat and carbon storage over tens to hundreds of years as well as the supply of heat to melt Antarctic ice shelves. With the goal of enhancing o

High Resolution Underway Air-Sea Observations in Drake Passage for Climate ScienceThe Antarctic Circumpolar Current (ACC) is the largest current on the planet, flowing west to east around Antarctica, forming a barrier that separates warmer waters to the north from colder waters to the south. Ocean eddies (like atmospheric storms) break through the ACC barrier, transferring heat across the ACC towards Antarctica. When warmer ocean waters intrude onto the Antarctic continental sh

CAREER: The Transformation, Cross-shore Export, and along-shore Transport of Freshwater on Antarctic ShelvesFreshwater discharges from melting high-latitude continental ice glacial reserves strongly control salt budgets, circulation and associated ocean water mass formation arising from polar ice shelves. These are different in nature than freshwater inputs associated with riverine coastal inputs. The PI proposes an observational deployment to measure a specific, previously-identified example of a coast

Collaborative Research: Impacts of Local Oceanographic Processes on Adelie Penguin Foraging Ecology Over Palmer DeepThe application of innovative ocean observing and animal telemetry technology over Palmer Deep (Western Antarctic Peninsula; WAP) is leading to new understanding, and also to many new questions related to polar ecosystem processes and their control by bio-physical interactions in the polar environment. This multi-platform field study will investigate the impact of coastal physical processes (e.g.

NSFGEO-NERC: Mechanisms of Adaptation to Terrestrial Antarctica through Comparative Physiology and Genomics of Antarctic and sub-Antarctic InsectsThe cold, dry terrestrial environments of Antarctica are inhospitable for insects, and only three midge species make Antarctica home. Of these, Belgica antarctica is the only species found exclusively in Antarctica, and it has been a resident of Antarctica since the continent split from South America ~30 million years ago. Thus, this species is an excellent system to model the biological history o

Collaborative Research: Sea ice as a driver of Antarctic benthic macroalgal community composition and nearshore trophic connectivityThe western Antarctic Peninsula has become a model for understanding cold water communities and how they may be changing in Antarctica and elsewhere. Brown macroalgae (seaweeds) form extensive undersea forests in the northern portion of this region where they play a key role in providing both physical structure and a food (carbon) source for shallow water communities. Yet between Anvers Island (64

Collaborative Research: Pathways of Circumpolar Deep Water to West Antarctica from Profiling Float and Satellite MeasurementsCurrent oceanographic interest in the interaction of relatively warm water of the Southern Ocean Circumpolar Deep Water ( CDW) as it moves southward to the frigid waters of the Antarctic continental shelves is based on the potential importance of heat transport from the global ocean to the base of continental ice shelves. This is needed to understand the longer term mass balance of the continent,

Protein Folding and Embryogenesis in Antarctic Fishes: A Comparative Approach to Environmental StressSince the advent of Antarctic continental glaciation, the opening of the Drake Passage between South America and the Antarctic Peninsula, and the onset of cooling of the Southern Ocean ~40-25 million years ago, evolution of the Antarctic marine biota has been driven by the development of extreme cold temperatures. As circum-Antarctic coastal temperatures declined during this period from ~20°C to t

Cold Corals in Hot Water - Investigating the Physiological Responses of Antarctic Coral Larvae to Climate change StressThe Western Antarctic Peninsula is experiencing climate change at one of the fastest rates of anywhere around the globe. Accelerated climate change is likely to affect the many benthic marine invertebrates that live within narrow temperature windows along the Antarctic Continental Shelf in presently unidentified ways. At present however, there are few data on the physiological consequences of clim

Collaborative Research: Benthic Faunal Feeding Dynamics on the Antarctic Shelf and the Effects of Global Climate Change on Bentho-Pelagic CouplingThe Antarctic Peninsula region exhibits one of the largest warming trends in the world. Climate change in this region will reduce the duration of winter sea-ice cover, altering both the pelagic ecosystem and bentho-pelagic coupling. We postulate that shelf benthic ecosystems are highly suitable for tracking climate change because they act as "low-pass" filters, removing high-frequency seasonal noi
