EP42A:
Patchiness in the Ocean: Exploring Environmental and Ecosystem Variability and Its Consequences, from Mesoscale to Fine Scale II


Session ID#: 37870

Session Description:
We are increasingly recognising the spatially patchy nature of the marine environment, with the oceans exhibiting high spatial variability in physical, chemical and biological parameters and animal behaviours at a variety of scales. This variability has significant implications for our understanding of ocean mixing, biogeochemistry, and ecology. Due to advances in technology, such as greater resolution in remote and acoustical sensing, the proliferation of underwater vehicles, and the ability to produce accurate 3-D hydrographic simulation models with high resolution, we are now capable of looking at smaller scale patterns and processes than ever before, and at linkages between physical, chemical, biological and ecological processes driving spatial variability. In this session we will explore mesoscale (around 100 km), sub-mesoscale (around few km) and smaller patterns (around 100 m) and processes driving patchiness, whether physical, chemical, biological, ecological, or, especially, interdisciplinary. We will look at how this patchiness can be sampled, described, and explained, and go beyond this to implications and consequences for biogeochemical processes, biological diversity and ecosystem dynamics, including implications for humans.
