Scientists deploy satellite tags on rarely studied sawsharks for the first time

Science

An Australian research expedition has successfully deployed three satellite telemetry tags on sawsharks for the first time! These rarely-seen sharks have a toothy rostrum similar to a sawfish, but are true sharks while sawfish are rays. Sawshark rostrums also have sensory barbels, unlike the rostrums of sawfish. “This is actually a good example of convergent evolution where two distantly related species have adaptations that have converged to be very similar in looks and (purportedly) function,”said professor Jane Williamson, the head of the Marine Ecology Group at Macquarie University and the leader of this expedition. “Sawsharks probably use their rostrum in a similar manner to sawfish: as a tool for sensing and capturing prey, and possibly for self-defense.”

Flotsam (what we’re obsessed with right now)

The poetry of Derek Walcott.

Nobel laureate, poet, and perhaps the finest English-language writer of any generation, died this weekend. His poetry, particularly the epic poem Omeros, which draws upon the themes of Homer’s Iliad and Odyssey to tell the story of colonization, imperialism, slavery, and humanity’;s relationship to the sea over more than 8000 lines.
If you’re new to the poetry of Derek Walcott, The Sea is History is a great place to start and the New York Times published a short selection of his poetry: The Pages of the Sea.

Conservation, Science

Shark wildlife tourism* is a growing marine industry with big implications for shark conservation. While there are many competing definitions, generally shark wildlife tourism refers to SCUBA dive operators who offer trips that guarantee that you’ll see sharks, often through the use of bait or chum to attract sharks to the divers. This has become a contentious issue in marine science and conservation circles. That’s why last week’s news that WWF, Project AWARE, and the Manta Trust released the first-ever guide to responsible shark and ray tourism best practices is so welcome. This thorough and well-researched guide guide is designed for dive operators who want to minimize their potential harm to sharks and rays while maximizing the potential conservation benefits of shark wildlife tourism.

The call of the Chthulucene ?

Climate change

We are currently in the Holocene epoch, and many of us have heard about calls to name the current era (from the industrial revolution) the Anthropocene (which dates back to at least the industrial revolution, if not before): a period when humans change the essential nature of the planet through their activities (primarily via the production of greenhouse gases).

But what comes after the Anthropocene? Some sort of Mad Max style wasteland perhaps?

Donna Haraway (2015) proposed that there will be a new epoch, the “Chthulucene” where refugees from environmental disaster (both human and non-human) will come together .

This weekend, the Washington Post reported on a leaked proposed budget from the Administration which includes drastic, agency-breaking cuts to the National Oceanic and Atmospheric Administration. This comes in the wake of new Commerce Secretary Wilbur Ross pledging to protect peer-reviewed researchers and shield NOAA climate scientists from partisan attacks and that the Department of … Read More “Monday Morning Salvage: NOAA Special Edition (call your representatives!)” »
