MAMMALIAN HEMOGLOBIN - Texas, California This project is looking at the absorption spectra of isolated hemoglobin that is
fully oxygenated and de-oxygenated. Where the two spectra cross over is
called the isobestic point.This point on the spectra is around 800 nm
in humans. Weare comparing the isobestic point
of isolated hemoglobin in marine mammals to humans.
LUNG FUNCTIONS - Texas, Hawaii, California, Massachusetts, Spain This project is analyzing and comparing the lung functions of several cetacean species. Using our modified equipment, we can look at flow rates during exhalation and inhalation as well as gas composition. We are comparing the lung function of captive animals in water and voluntarily beached to wild animals that have stranded for unknown causes. This research will give us insight on how gravity may affect the animals ability to exchange gas while on land.
MICROPARTICLES - Vancouver, Massachusetts We are studying whether microparticles, a constituent in blood,
can be a biomarker of decompression stress. Without a
measurable indicator, decompression stress
has been difficult to accurately diagnose in stranded marine mammals.
We are testing whether a relationship between decompression stress and
microparticles levels exists. If confirmed as a biomarker,
microparticles have the potential to be used as a diagnostic tool during
PHOTO IDENTIFICATION - Texas The central coast has little to no information on the number of resident bottlenose dolphins in the Port Aransas shipping channel. A team of lab members, students, and volunteers has been using photo identification to estimate the population of animals in the area anddetermineresidentialvs.transientanimals. We are also hoping to establish the primary use of this area whether it be fishing, calving, resting, etc.
