Dead whales, glass sponges, 3D-printing for the ocean, and more! Weekly Salvage: October 14, 2019
Deep-sea gator falls covered in isopods, more struggles for the Ocean Cleanup, a robot lost in the cold (but not the one you’re thinking of), and more! Monday Morning Salvage: February 18, 2019

Flotsam (what we’re obsessed with right now)
What do you do if you find yourself at the helm of a major Louisiana marine science institution? If you’re Dr. Craig McClain, you plant the first experimental Alligator falls in the deep Gulf of Mexico!

On the other hand, if you find yourself at the helm of a US Navy destroyer, you might want to review this incredible and exhaustive accounting of the USS Fitzgerald disaster and how training deficits, exhaustion, and poor decision making compounded to create a deadly situation.

- Canada is flying blind into Arctic Conservation. By Cody Dey, for the Narwhal, about research I’m a coauthor on (Cody is lead author). We’re excited about this paper, which, among other things, shows major gaps in the research and understanding of many Arctic fishes. This is a big problem as Arctic fishing is only going to increase in frequency.

Plumbing the depths (discussion):
- An unprecedented number of scientists are running for elected office in the United States this year… but is that a good thing? I do not see how an elected official who is a trained scientist will be a stronger advocate for science than an elected official who has a good scientific advisor that they listen to, and the latter has many advantages over a scientist. (Obviously a scientist in office is better for science than an anti-science idealogue). What do you think? Let us know in the comments! And check out Maggie Koerth-Baker‘s excellent in-depth article about this for 538.

I asked 15 ocean plastic pollution experts about the Ocean Cleanup project, and they have concerns
The online ocean science community has been vocally skeptical about the Ocean Cleanup, a device that aims to physically remove plastic pollution from the ocean. Drs. Kim Martini and Miriam Goldstein published a technical review of its feasibility over at Deep Sea News, and Andrew asked some important questions that have yet to be answered. Also, be sure to read environmental journalist Chris Clarke’s thorough overview of these concerns.
Overall concerns include a lack of understanding of the problem (including but not limited to the fact that much of the harmful ocean plastic is small and well-dispersed), insufficient structural integrity for a large object that will be deployed in the open ocean (which would result in the object breaking and creating even more ocean garbage), and the fact that this device is designed to aggregate objects of a certain size to remove them from the water but cannot distinguish between plastic and living things.
Mainstream media coverage has been noticeably less critical of the Ocean Cleanup, often presenting the idea as revolutionary and it’s creator as a genius.
I am not an expert in ocean plastic pollution. However, the uncritical tone of most mainstream media coverage of the Ocean Cleanup does not seem to correspond with my impression of expert opinion on this matter from speaking with expert colleagues who study this.
Through professional contacts, I developed a list of 51 ocean plastic pollution experts who work in academia, government, and the environmental non-profit sector, and I sent them some questions about the Ocean Cleanup. 15 (4 in academia, 5 each in government and the non-profit sector, and 1 in industry) agreed to participate in an anonymous survey. While this is not (and not intended to be) an exhaustive survey of the entire field of ocean plastic pollution, the broad agreement among a diverse group of experts is telling. Below, please see what they had to say through some representative quotes. Some respondents chose to provide an on-the-record quote, while many chose to remain anonymous out of concerns about reprisal.
I also asked Lonneke Holierhoek, COO of the Ocean Cleanup, to respond to these concerns. Her comments are included in each section.
