New theory of deep-ocean sound waves may aid tsunami detection

Researchers have now identified a less dramatic though far more pervasive source of acoustic-gravity waves: surface ocean waves, such as those that can be seen from a beach or the deck of a boat. These waves, known as surface-gravity waves, do not travel nearly as fast, far, or deep as acoustic-gravity waves, yet under the right conditions, they can generate the powerful, fast-moving, and low-frequency sound waves.

Sea Shepherd and the Animal Legal Defense Fund File Motion to Intervene in Seaworld V. Calif. Coastal Commission Lawsuit

Organizations Determined To Prevent More Orcas from Suffering in Captivity

Sea World San Diego killer whale show (courtesy Wikimedia)Sea Shepherd Conservation Society and the Animal Legal Defense Fund (ALDF) filed a motion together to intervene in the SeaWorld v. California Coastal Commission lawsuit in the California Superior Court in San Diego. The organizations seek to help uphold the conditions that the Commission imposed on SeaWorld San Diego’s coastal development permit on October 8, 2015. The permit conditions, which restrict breeding and transfer of orcas by Sea World, effectively require the amusement park to phase out its captive orca program if it chooses to go forward with plans to expand its facility.

On December 30, 2015, SeaWorld filed a lawsuit against the California Coastal Commission challenging the Commission’s decision to condition approval of SeaWorld San Diego’s permit to modify its orca exhibit upon an express prohibition on the use of the modified tanks for any orcas other than the eleven specific orcas already housed at SeaWorld San Diego. Indeed, by prohibiting captive breeding, wild capture, transfers, or other replacement of orcas, the permit conditions ensure that SeaWorld San Diego’s captive orca program will come to an end if Sea World begins work under the permit.

ALDF, who originally proposed those permit conditions with a coalition of other organizations, and SSCS are seeking permission from the court to join the lawsuit as third party defendants to ensure that the permit conditions remain in place.

“The California Coastal Commission has the authority and the duty to conserve marine resources, including captive orcas,” said Stephen Wells, executive director of the Animal Legal Defense Fund. “The Commission’s decision was informed by detailed analysis of its obligations under the California Coastal Act and extensive input from internationally renowned cetacean experts about the negative impact of captivity on orcas. As an organization that proposed the permit conditions, ALDF has a vested interest in making sure those conditions are upheld in court.”

Commenting on the Commission’s decision, Sea Shepherd founder, Captain Paul Watson, stated: “Though the permit was not denied, it was still a win for the whales as the Commission may have forced SeaWorld to begin to make significant changes to the way it operates, and sent a strong message that the public is only interested in an endeavor that will truly benefit the whales and not SeaWorld’s profits.”

Sea Shepherd Crew Save Humpback Whale Entangled in Illegal Gillnet

Sea Shepherd Crew Save Humpback Whale Entangled in Illegal Gillnet

Mexican Navy assists SSCS helping the whaleOn February 19, 2016, the crew Sea Shepherd's research vessel of R/V Martin Sheen spotted a humpback whale entangled in a gillnet in the Vaquita Refuge in the Gulf of California, Baja California, Mexico. While Captain Oona Layolle, campaign leader and captain of the M/V Farley Mowat, notified the Mexican Navy and the Federal Attorney for Environmental Protection (PROFEPA), the crew began the rescue operation. The whale was estimated to be 35 feet long and crews from both vessels worked to free the whale by cutting the gillnet off the whale's head and torso.

This is not the first humpback whale entangled in an illegal gillnet found by Sea Shepherd crew. On Christmas Eve, the crew of the R/V Martin Sheen spotted a humpback whale weighed down by a gillnet. Upon further investigation, the crew determined that the humpback whale was a calf and was already dead. Sea Shepherd then sought permission from the Mexican government to be able to begin removing gillnets; that permission was granted on December 31, 2015.

Sea Shepherd's newest vessel, the M/V Farley Mowat, a retired United States Coast Guard interceptor ship, joined the R/V Martin Sheen, in January 2016. On its first day of Operation Milagro, the crew of the M/V Farley Mowat spotted an illegal gillnet and spent six hours removing it. The Mexican Navy were notified and seized the illegal gillnet. Since then, the crews of both vessels have developed net retrieval devices to trail behind the R/V Martin Sheen and the M/V Farley Mowat's speedboat the Wolf. The use of these devices has already resulted in removal of seven gillnets and three longlines in just the past few weeks. Three totoaba, seven rays, one whale, and dozens of juvenile sharks have been saved by the recent removals of illegal fishing equipment. This total does not taken into account the countless animals who will not become trapped and die in the illegal gillnets and illegal fishing lines.

The crew of the M/V Farley Mowat was recently joined by Survivorman Les Stroud. Upon assisting in freeing the whale, he commented, “This is true conservation in action. Today, we were able to save the whale and remove another illegal gillnet. It is an honor to be a crew member with Sea Shepherd Conservation Society. Cutting that net and freeing the whale was a life changing experience.”

In April 2015, President Enrique Peña Nieto announced a two year ban on the use of gillnets in the Gulf of California. The intent was to protect the vaquita porpoise, the world's most endangered marine mammal. Vaquita are the unintended victims of gillnets used to catch the totoaba bass, another endangered species. The totoaba are targeted for their swim bladders for sale on the black markets in Asian. Vaquita are native only to the northernmost part of the Gulf of California.
