Updates from the Deep: New and Noteworthy in Hydrothermal Vent Research

From hairy-chested yeti crabs to the deepest known fields, hydrothermal vents have been enjoying a bit of science celebrity in the last few weeks. Beneath the headlines, there has been an eruption of vent-related research published in the scientific literature and some exciting new expeditions just left port.

The Discovery of New Deep-Sea Hydrothermal Vent Communities in the Southern Ocean and Implications for Biogeography

The exhaustive author list on this paper reads like a who’s who in hydrothermal vent biogeography. This is the paper that introduced “the Hoff” crab to the world, but the findings are far more significant. Hydrothermal vent systems are sorted into biogeographic provinces, with different regions supporting different communities. The iconic giant tube worms dominate the eastern Pacific, while the western Pacific (prominently featured in Deep Fried Sea) plays host to fist sized snails, and the Atlantic features shrimp as its dominant species. There are several missing gaps in our understanding of how these qualitatively different communities are connected – the Southern Ocean, the south Atlantic, the Indian Ocean, and the Cayman Trough, among others. Filling in these gaps in our knowledge can help us understand the history and evolution of hydrothermal vent ecosystems.

Is Sea Shepherd really saving whales?

Sea Shepherd claims that their actions in the Southern Ocean opposing Japanese whaling fleets has effectively reduced the number of whales killed. What always rubbed me the wrong way about these claims is that they always compare their success against the Institute for Cetacean Research (the Japanese organization that oversees ‘scientific whaling’) Quotas. So at some point you have to ask the question, in absolute numbers, has Sea Shepherd really reduced the number of whales killed?

To answer that we need three pieces of information:

When did Sea Shepherd begin it’s campaign against Japanese ‘scientific whaling’?
What are the ICR quotas for that time frame?
What are the absolute catches for that time frame?

Sea Shepherd provides a comprehensive timeline for their whaling campaigns that indicates serious opposition in the Southern Ocean began in December 2002. For the two other questions, we turn to Whale and Dolphin Conservation International, who have produced a truly exceptional interactive graph of the history of whaling since the inception of the International Whaling Convention by the numbers. The relevant figure is reproduced below:

This time they’ve gone too far. In this economy, it’s hard enough to find employment as a marine scientist. Marine mammals are taking our jobs!
