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.

Artist’s conception of the Ocean Cleanup, from TheOceanCleanup.com

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.

Have you heard the good news about shark populations? Shark population increases are cause for #OceanOptimism

Did you know that some shark populations have declined due to overfishing? Did you know that some once-declined shark populations have recovered? If you’re like my twitter followers, it’s likely that you’ve heard the bad news, but have not heard the good news.

Why does this matter?
It’s important to share bad news so that people know there’s a problem, and that we need to act to solve that problem. However, it’s also important to share good news so that people know that a problem is solvable! This idea was behind the birth of the #OceanOptimism online outreach campaign.

Protect Our Oceans: from the ground in Guam and the Commonwealth of the Northern Mariana Islands

Carlotta Leon Guerrero is a former Member of the 23rd, 24th, and 25th Guam Senate. She was also a two-term president of the Association of Pacific Island Legislatures and previously worked as a radio and television journalist in Guam and the Northern Mariana Islands.


In April 2017, President Donald Trump ordered Secretary of Interior Ryan Zinke to examine 27 protected areas established by Presidents Bill Clinton, George W. Bush, and Barack Obama using the 1906 Antiquities Act.  Included in the list were four marine monuments in the Pacific Ocean, the Papahanaumokuakea Marine National Monument in Hawaii, Mariana Trench Marine National Monument in the Mariana Islands, Rose Atoll Marine National Monument in American Samoa, and the Pacific Remote Islands Marine National Monument (sometimes referred to as Pacific Remote Island Areas or PRIA), which is made up several isolated islands and atolls under American control.  This should have all of us on Guam and in the Pacific concerned, because we are the people who will have to live with the outcome.

How to spot a scam shark documentary producer

Many aspects of science-ing are not explicitly taught, and scientists become accustomed to mastering the deep end.  While this tactic can make you stronger, there are situations where the deep end is a vulnerable place where nasty critters are very happy to take advantage.

One such area?  How to handle being contacted by “producers.”  In my experience, for every 1 exceptional producer you speak with, you will be contacted by at least 4 scammers.  Scam producers will particularly target naïve early-career scientists, just like white sharks and seal pups.  In light of this week, I’ve put together a guide to aid YOY scientists rising in the ranks of popularity and make the deep end a little safer.  Here are 13 ways to spot scam shark documentary producers, with a few 🚩🚩:

37 things I learned about shark ecology and conservation for my dissertation

The fam attending my dissertation defense

The fam attending my dissertation defense

After a little more than 5 years of hard work, I’ve officially completed my Ph.D.! You can read my dissertation (“An Integrative and Interdisciplinary Approach to Shark Conservation: Policy Solutions, Ecosystem Role, and Stakeholder Attitudes”) online here in its entirety.

In case there are some among you who don’t really want to read a 281 page dissertation but are curious about what I found, I’ve prepared this blog post to summarize my key conclusions. (Note: this does not include every conclusion. Some are aggregated together, and some more technical conclusions are omitted for this summary).

Time to release the Kraken ! Addressing controversial questions in marine conservation

A few years ago, we organized a group of marine conservation scientists to meet to discuss, and list,  the most urgent issues that need to be studied. The resulting paper  came up with 71 questions which urgently needed to be addressed, because a lack of an answer was severely impeding marine conservation. However, during this exercise we also came up with a list of other questions – these were issues that were controversial, that everyone  knew were important, but were unwilling to raise as being an issue. These were the Voldemorts of marine conservation questions (they that shall not be named), the elephant (or elephant seal) in the room questions …. or as we more aquatically termed them: “the kraken in the aquarium” questions.

Trading blue collars for scarlet robes, my working-class experience of academic life

More people are going to college, graduate school, and obtaining PhDs in STEM fields than ever before (Figure 1), and a growing minority of these PhD candidates are non-traditional or not white affluent males. While we celebrate this change, let us not forget that academia was built by – and for – the “traditional” student. My favourite analogy to explain this type of ingrown privilege is bicycles on USA streets. Bicycles are legally allowed to be on streets, some streets even have extra space just for bicycles, but streets were designed for automobiles. You may be allowed and, in some areas, encouraged to get on the street with your bicycle, but biking a street is going to be intrinsically more difficult than if you were driving a car.

Like Marconi and La Bamba in a city built on rock and roll, you will inevitably end up in situations that conflict with your way of life. You will not receive a warning before you stumble upon these bumps, and you will be judged by how quickly you accept traditional standards (if you can).  I remember a conversation with traditional tenured and tenure-track scientists discussing proposals for a large grant scheme. One tenure-track scientist was lamenting the process of shopping for editors for his proposal. He talked about it freely, how there were two companies that charged different rates and he was in talks with one but that company felt a conflict of interest that he had worked with another rival editing company. The rest of the traditional scientists nodded in mutual understanding. Finding good, cheap editors to improve your work is hard. My working-class ethos was busy screaming inside my head.  How can hiring someone to edit and improve written works that you will ultimately be rewarded for be so blithely acceptable? You’re not allowed to hire editors for any task throughout your training. You learn how to write from earning disappointing grades (or failing grant applications). You read more, you study written works, you develop a voice, and you try again. The results get better until you are at an appropriate level to move up another notch on the ladder, right? Not for traditionals.

Here are some more bizarre “traditional” customs you should expect if you are biking down the academic street:

The difference between animal welfare and animal rights

I have just attended a big international conservation meeting for the past week and there was a lot of discussion about the “Cecil the Lion Phenomenon.” In many discussions, the terms animal welfare and animal rights were brought up frequently, and it was very clear that many conservation scientists do not know the difference between the terms, or the differences between those who advocate on issues that are more about individuals than species or populations. When the term “welfare” was brought up, it was often with scorn and PETA was almost always the organisation that was given as an example. This really does show a fundamental lack of understanding about advocates and organisations that represent individual animals, and that could be major (even essential) assets and allies in conservation.

The terms “welfare” and “rights” cover a wide spectrum; lumping them together is like lumping Democrats (left wing liberals) and Republicans (right wing conservatives) together and making no distinction because they are both political parties. There are nuances, but as a basic primer, here are some (very) approximate distinctions:
