In general, animal song is thought to have several specific characteristics including being restricted to males, having a territorial purpose, and being used to attract a mate. Join marine acoustics expert John Hildebrand to learn how the singing characteristics in some whale species challenges this generalization and how long term trends in whale song still present a mystery to scientists.

The ocean plays a major role in regulating Earth’s temperature through exchange of chemicals and microbes with the atmosphere. When waves break, ocean-derived biological species including viruses and bacteria are transferred into the atmosphere. These species can ultimately form clouds, altering precipitation and climate. Highlights will be presented of novel experiments being conducted in a unique ocean-atmosphere simulator developed by the National Science Foundation (NSF) Center for...

Collapsing ice shelves and calving of large icebergs in Greenland and Antarctica have recently become major drivers of sea level rise. The rapidity of these changes has come as a surprise, revealing major gaps in our understanding of how ice sheets respond to a changing climate. To a large extent, these gaps are due to the lack of measurements from the marine edge of glaciers - the Achilles' heel of glaciers. For over a decade, since the glaciers in Greenland began their retreat, Fiammetta...

Sooner or later, the food requirements of nine billion people with increasing appetites for seafood must be addressed. Although aquaculture may supply the majority of the global ‘seafood’, most aquaculture is fed meal from wild caught fish, such as sardine and anchovy. To estimate the distributions and abundance of these and other small fish off the west coast, NOAA Southwest Fisheries Science Center routinely conducts “acoustic-trawl” surveys. David Demer will briefly describe the vessels,...
