A Wealth of Data in Whale Breath
Researchers are studying the breath of marine mammals in captivity in order to improve their health and to develop an effective, unobtrusive technique for studying them. Blood is the “gold standard” in for health research, but it is extremely difficult to obtain from larger animals. By studying the breath produced from the whales’ blowhole, researchers can learn almost as much without any invasive procedures. Trainers and veterinarians working with captive whales routinely smell their breath. By now they know that normal, healthy breath has a fishy smell; rotten-egg breath indicates digestive problems and sweet-smelling breath indicates bacterial pneumonia. They can also identify many hormones that can indicate the animals’ sex, maturity,reproductive status and stress levels.
Food security ‘under threat’ as oceans suffer under climate change
The International Panel for Climate Change (IPCC) recently released a report on the science of climate change which reveals that it is as much a problem for the oceans as it is for land. The report found that sea levels have risen an average of 19cm since 1901 and are expected to continue to rise 26cm more by the end of the century. The report also highlights the issue of ocean acidification and warming oceans, all of which have implications for global food security as populations shift and habitats are destroyed.
Last month, the National Oceanic and Atmospheric Administration’s Fisheries Service officially denied the Georgia Aquarium’s request to import 18 wild-caught Beluga whales into the US. Yesterday, the Georgia Aquarium headed to court in an attempt to overturn NOAA’s ruling. This was the first time in more than 20 years that a US facility has attempted to import marine mammals captured from the wild specifically to be put on display. NOAA maintains that taking those belugas would threaten the wild population, but the aquarium states that the permit met all the required criteria under the Marine Mammal Protection Act.
