Hyperbaric oxygen-induced seizure in a marine mammal, the seal.

KEREM, DAN,GERALD KOOYMAN,JOSEPH P. SCHROEDER,JAMES J. WRIGHT, AND CHARLES M. DRABEK. Hyperbaric oxygen-induced seizure in a marine mammal, the seal. Am. J. Physiol. 222(5) : 13221325. 1972.-A female yearling northern elephant seal, Mirounga angustirostris, and a female yearling harbor seal, Phoca vitulina were subjected to breathing oxygen at a pressure of 4.5 Ata in the restrained unanestheti...

Elevated carboxyhemoglobin in a marine mammal, the northern elephant seal.

Low concentrations of endogenous carbon monoxide (CO), generated primarily through degradation of heme from heme-proteins, have been shown to maintain physiological function of organs and to exert cytoprotective effects. However, high concentrations of carboxyhemoglobin (COHb), formed by CO binding to hemoglobin, potentially prevent adequate O2 delivery to tissues by lowering arterial O2 conten...

FINAL REPORT Predictive Spatial Analysis of Marine Mammal Habitats

The effect of experimental instructions on the number of areas identified as important in photographic images

A study is underway aimed at increasing understanding of the design of pictorial stimuli in perceptual experiments. Since this work centers on pictorial scenes, a variety of such scenes must be selected as stimuli. The experiments planned require scenes that are perceived to have at least five key areas of interest. Further, each of these must be able to be cropped to versions perceived to have...

Assessing the Deepwater Horizon oil spill impact on marine mammal population through acoustics: endangered sperm whales.

Long-term monitoring of endangered species abundance based on acoustic recordings has not yet been pursued. This paper reports the first attempt to use multi-year passive acoustic data to study the impact of the Deepwater Horizon oil spill on the population of endangered sperm whales. Prior to the spill the Littoral Acoustic Demonstration Center (LADC) collected acoustic recordings near the spi...
