Mammals show an increase in heart rate when breathing in and a decrease during expiration -- a cardiorespiratory process known as respiratory sinus arrhythmia (RSA). This process and its underlying control mechanisms have been considered by many scientists to be solely mammalian but the present ...
“Marine mammals are very sensitive to noise, and all this additional shipping in these waters might create an impact by the introduction of noise,” Antunes said. Scientists have used satellite tags and aerial surveys to track mammals in the Bering Sea, but Antunes said a study like this one is something new.
To most people, the ocean environment seems like one of serene silence. In reality, it's a smorgasbord of sound. And not all of the noise is helpful to the marine life inhabiting it. In January, the Trump administration proposed opening up more than 90 percent of U.S. coastline to offshore oil and gas drilling.
What the sounds show right now—the baseline Antunes talked about—is not surprising: ships pass through in the summer, and marine mammals are most common in the winter, when sea ice locks up the Bering Strait and St. Lawrence Island. Seals and walrus use that ice to haul out, and hunters use it to ...
Scientists tested the accuracy of determining marine mammal size by analyzing aerial photography taken from a small drone as a less costly, less stressful alternative to manual capture and measurement. To be precise in their measurements of leopard seals, the researchers took overhead photographs at ...
