From March 8th<\/sup> to the 19th<\/sup> 2017, Sea Shepherd\u2019s R\/V Martin Sheen<\/em> welcomed four scientists under the supervision of Dr. Jorge Urban, from Universidade Autonoma de Baja California Sur (UABCS) and sailed to the remote Archipelago of Revillagigedo for scientific studies.<\/p>\n Revillagigedo is a UNESCO World Heritage Site in the Pacific Ocean that is made up of four volcanic islands approximately 240 miles southwest of Cabo San Lucas, in the Baja California Peninsula, Mexico.\u00a0 These include three inner islands, San Benedicto, Socorro and Roca Partida, and the outer island, Clarion.<\/p>\n This archipelago is one of the most important breeding areas in Mexico for the humpback whale, who migrate to the location from various feeding grounds in Alaska and the Bering Sea.<\/p>\n “The humpback population found here demonstrates a high loyalty to this archipelago,\u201d said UABCS\u2019s Pamela Martinez, who was on board the Sheen.<\/em> \u201cThis research project is important to help determine the current conservation status of these whales and to gather information about their migration patterns and migration connections between their feeding and breeding grounds.”<\/p>\n The visiting scientists took photographs to identify the individual humpback whales on the archipelago\u2019s Socorro and Clarion Islands.\u00a0 They also took skin and blubber biopsies which helps with determining the gender of the whales along with what they have been eating.\u00a0 Sound recordings of humpback whales were also conducted.<\/p>\n Scientists hope to use the collected data to confirm that these whales are not always migrating in the same patterns. Martinez believes that humpback whales are mostly loyal to their breeding grounds, but not always loyal to their feeding grounds.<\/p>\n httpv:\/\/www.youtube.com\/watch?v=ETvZI1hjVVE<\/p>\n Microplastics in the Oceans<\/strong><\/p>\n While in Revillagigedo, scientists also took water samples to identify if there are any microplastics in the water. Plastic is the most common debris found in Oceans; those less than 5mm are referred to as \u201cmicroplastics.\u201d<\/p>\n The project continued the work started last year with Sea Shepherd and UABCS in the same area. At the time, scientists discovered the archipelago\u2019s Clarion Island – the one furthest away from land – had the highest concentration of microplastics of all four islands. Last month\u2019s expedition with Sea Shepherd was a follow-up to collect more samples and investigate if this still holds true.<\/p>\n Whale tail.
