Betty - November 14

Betty continues moving east through the middle of the Gulf of Mexico, south of Louisiana/Mississippi.

Last week she made a few dives to a depth of 400-500 m, and even one dive to 500-600 m. They lasted up to 11-15 minutes in duration.

Betty continues to move to the east through the deep water south of Louisiana.

Betty - November 12

Betty has moved offshore a bit, south of Louisiana, to waters about 2000 m deep. She has been making a few dives to 300-500 m, but the vast majority of dives continue to be to less than 50 m. Over the past few days, she has made dives lasting as long as 9-10 min, but mostly they are 3-4 min or less. She has sent nearly 11,000 transmissions (of 25,000 projected total) and battery voltage continues to be strong.

Betty - November 11

Betty continues to the east along the edge of the continental shelf south of Louisiana. Betty's tracking has now continued for twice as long as was possible for Clyde, the last Risso dolphin tracked.

Betty - November 10

Betty continues moving to the east along the shelf edge south of Louisiana. She appears to be in the vicinity of a fair amount of oil production activity. Maybe she wants to see what a $100 barrel looks like...

Betty - November 9

Betty continues moving slowly to the east to the south of Louisiana, roughly zig-zagging over the 200-1000 m slope.
