Because OpenROV Trident is a work of art and should be displayed as such when not on deployment. This was my first big design project using the Glowforge and integrating LED strips If you have a Trident, you can download the plans and bill of materials right here: OpenROV Trident Glowing Wall Mount. More importantly, if … Read More “I made a ridiculous Glowing Wall Mount for my OpenROV Trident!” »
Recently, the Canadian government released the Final Report of the National Advisory Panel on Marine Protected Area Standards. This report is a set of guidelines and goals for the creation of new marine protected areas in Canada, and comes as Canada is hoping to greatly increase the number and quality of MPAs. I reached out to MPA experts and environmental nonprofits to ask what they think.

Barndoor skates were once thought to be so overfished that a highly-publicized paper from 1998 noted that they had been “driven to near extinction without anyone noticing.” One of the largest skates, barndoor skates can reach over 5 feet in wingspan, which is large enough that their diet includes small sharks like spiny dogfish; for a skate, that’s about as close as it gets to charismatic megafauna!
Recently, NOAA Fisheries announced that Barndoor skate populations off the Northeastern United States had finally recovered enough that fishing for them could resume. This move comes after a 2009 NOAA Fisheries report showed that the species had begun to recover enough that they could be removed from the species of concern list, though they remained protected at the time. “This is good news,” Mike Ruccio, a Supervisory Fishery Policy Analyst for NOAA Fisheries Greater Atlantic Regional Fisheries Office, told me. “Rebuilding overfished stocks is one of the cornerstones of the US domestic policy on fisheries.”

Foghorn (A Call to Action!) The new IPCC Climate Change Report is out and it is grim.

Two weeks ago, tragedy struck in New England as a boogie boarder was killed by a great white shark. Though shark bites* in general and fatal shark bites* specifically are incredibly rare (Mr. Medici was the first person killed by a great white shark in Massachusetts waters in 82 years), emotions are running high. Some Cape Cod residents are explicitly calling for a cull (targeted killing) of great white sharks.
Such a cull would be devastating for a recovering but still protected shark species, has been shown not to effectively reduce shark bites, and is opposed by shark experts around the world, but what, if anything, should local governments do instead? I’ve written in the past about alternatives to lethal shark control here and here, but not every solution is applicable for every location; local oceanographic conditions vary, as well as local laws and cultural norms. I reached out to three experts to ask what, if anything, they think should be done here. Here’s what they had to say:
