What We Will Do for the next 30 Minutes § What’s it like to be at sea? § What instruments do scientists use at sea? § What data is collected at sea? § What do we do with the data? What does it tell us? § You too can be part of this – there a lot of people involved!

Going to Sea: Where?

Why the Bering Sea? (not because we like “The Deadliest Catch” § Originally (1984)

Why the Bering Sea? (not because we like “The Deadliest Catch” § Originally (1984) – Study the relationship between the marine environment and fish (pollock) § In the 90’s – Study the relationship between the Bering Sea and Gulf of Alaska ecosystem and marine resources.

What do we do when we get there? Deploy Drifters to track currents Deploy

Putting it all together: What story does the data tell? Is it getting warmer

Putting it all together: What story does the data tell? Is it getting warmer in the Bering Sea?

Putting it all together: What story does the data tell? Conditions on the Eastern

Putting it all together: What story does the data tell? Conditions on the Eastern Bering Sea Shelf. May 2005 - September 2006 2005 2006 Two distinct regions of the Bering Sea

Putting it all together: What story does the data tell? Currents affect where larvae

Putting it all together: What story does the data tell? Currents affect where larvae go, which affects how many make it to adulthood, which affects how many fish can be caught!
