NPR/NGS RADIO EXPEDITIONS LOG -Elephant Seals DAT #1 Ano Nuevo -with Bernie, LeBoeuf [BLB] -on the beach MS -stereo - Engineer -Leo Walking to the beach with Burney LeBoeuf (BLB) Chatter with grad/research students Trying to record elephant seal bulls fighting in the water 10:109 Alex screams "OOOOOH, look at that.....that one animal just sunk its teeth into the chest of another..... Carolyn, you want to keep an eye behind us..... [Alex screams again] ....waves .....Alex says: animals cut and bleeding in the chests, blood just pouring out of them... BLB: Now typically if this were the alpha male of the harem and he won the fight and the fight ends.....the loser would go away, the winner would come back to his harem... it's at a time like that the beta male, the second male in command would challenge him....now is the time to make a move, they're smart animals..... AC: [12:14] look at that + waves, one will sink his enormous jaw into his chest.... and then yank the animal under water. 12:47 BLB: The consequence of a fight like this are very important.

The idea is to try to get a really good idea of where she goes and how she spends her time at sea.... foraging, what she's eating....during huge amount of time when she's not on the beach...what we do with it is go in and analyze dive records... 8 months worth of diving data.... lot of computer processing involved...go through break up dives .. different kind of wave patterns -foraging strategies... actual device six inches long and an inch in diameter, so it's a pretty small unit -microelectronics -measures diving depth of animal the entire time at sea....detailed picture of every single dive while animal is at sea, how deep it dove, how fast it got to that depth, and we can construct a picture of daily life of seal over 8 months .... attached? marine epoxy glued to fur of the animal.....she'll molt that off i...
