EP24C:
Open-Ocean Biological-Physical Interactions in the Eastern North Pacific from Low to Middle Latitudes Through in Situ Observations, Satellite Data, and Models Poster Lightning


Session ID#: 38883

Session Description:
The Eastern North Pacific is an area where biological systems are impacted by a variety of physical processes at spatial scales ranging from sub-mesoscale through basin-scale. At low latitudes, the East Pacific includes the high nutrient low chlorophyll region of the cold tongue where mechanisms linked to shifts in biological production range from short-term turbulent mixing to periodic oscillations (e.g. ENSO). Meanwhile, the North Pacific Subtropical Gyre (NPSG) is somewhat of an enigma as an oligotrophic region with low nutrient levels that nonetheless supports dramatic summer phytoplankton blooms as well as the White Shark Cafe, where otherwise coastal great white sharks tend to congregate in winter and spring for reasons not yet understood. The recent advances in systems that observe biological variables (e.g. Bio-Argo floats) combined with two decades of global measurements from ocean color satellites and in-situ measurements, such as from the Hawaii Ocean Time-series (HOTS) program, provide an opportunity to explore this subject with more assets than ever before. This session will explore links between physical signals and biological variability in the Eastern North Pacific from low to mid latitudes with implications for long-term changes and regime shifts in biology.
