3 August 09 Survey

This morning dawned unusually cloudy for this time of year. It was calm enough for the visual observers to work, but they needed to bundle up to stay warm. The wind came up by the afternoon, making it difficult to sight whales, but the acoustic monitors kept listening. At the same time, the engineers on the ship were working on troubleshooting one of the systems designed to measure the bearing to echolocating beaked whales.

At this point we have done 4 legs of the survey designed for the Balearic Sea with very few detections of marine mammals other than dolphins. There appears to be a much lower rate of detecting deep divers than in the Alboran Sea, so we have decided to transit to the Alboran Sea. On the transit we passed near Mallorca as the moon rose.
