Over 15 years of ocean science and conservation online
Today, there are more robots exploring the ocean than ever before. From autonomous ocean-crossing gliders to massive industrial remotely operated vehicles to new tools for science and exploration that open new windows into the abyss, underwater robots are giving people a change to experience the ocean like never before. The fastest growing sector of this new robotic frontier? Small, recreational, observation class ROVs.
Today, we published our guidelines on the responsible operation of small recreational ROVs around marine mammals.

Reprinted below are the explicit guidelines proposed in the paper.
1. Education. Central to any mitigation strategy involving diverse stakeholders, ranging from professional to recreational, is user education. The following are critical to establishing a responsible user community: Ensuring all potential microROV users 1) not only understand the laws and regulations for wildlife viewing that apply to the jurisdiction in which they are operating, but understand why those regulations are in place; and, most importantly, 2) have internalized a stewardship ethic that motivates them to respect the rationale behind those regulations even when operating in regions where those regulations are not enforced. This is most effective when it occurs at point-of-sale or registration of the microROV. Thus, while the additional four guidelines relate to the user, this first one relates to the manufacturer. To most effectively convey the potential harm that microROVs could pose to marine mammals, the manufacturers are best positioned to educate their user base by providing informational material with each microROV sale.

I want to change gears this afternoon and talk about a very different kind of mining. For the last two years, Diva and I have been engaged in a data mining project to discover what we can learn and what we still need to learn about biodiversity at hydrothermal vents from the 40-year history of ocean exploration in the deep sea.
“When the RV Knorr set sail for the Galapagos Rift in 1977, the geologists aboard eagerly anticipated observing a deep-sea hydrothermal vent field for the first time. What they did not expect to find was life—abundant and unlike anything ever seen before. A series of dives aboard the HOV Alvin during that expedition revealed not only deep-sea hydrothermal vents but fields of clams and the towering, bright red tubeworms that would become icons of the deep sea. So unexpected was the discovery of these vibrant ecosystems that the ship carried no biological preservatives. The first specimens from the vent field that would soon be named “Garden of Eden” were fixed in vodka from the scientists’ private reserves.”
Thaler and Amon 2019
In the forty years since that first discovery, hundreds of research expedition ventured into the deep oceans to study and understand the ecology of deep-sea hydrothermal vents. In doing so, they discovered thousands of new species, unraveled the secrets of chemosynthesis, and fundamentally altered our understanding of what it means to be alive on this planet. Now, as deep-sea mining crawls slowly towards production, we must transform those discoveries into conservation and management principles to safeguard the diversity and resilience of life in the deep sea.
Though research at hydrothermal vents looms large in the disciplines of deep-sea science, relative to almost any terrestrial system, they are practically unexplored. Over the last 2 years, Drs. Andrew Thaler and Diva Amon have poured through every available cruise report that made a biological observation at the deep-sea hydrothermal vent to assess how disproportionate research effort shapes or perception of hydrothermal vent ecosystems and impacts how we make management decisions in the wake of a new form of anthropogenic disturbance.

In 2001, on an expedition to hydrothermal vent fields in the Indian Ocean, researchers made a bizarre discovery. Clustered in small aggregations around the base of a black smoker was an unusual snail, seemingly clad in a suit of armor. Rather than a single, hard, calcareous structure, the snail’s operculum was covered in a series of tough plates. On recovery to the surface, those plates, as well as the snail’s heavy shell, began to rust. This was an Iron Snail.

I can’t imagine a more useful introductory reference guide for new or prospective graduate students starting their career in marine biology than “Shark Research: Emerging Technologies and Applications for the Field And Laboratory”. This book is designed for people who have little to no familiarity with a research discipline but are about to start working in that discipline, a large and important audience that is often ignored by books and review papers geared towards people who are already experts. So many graduate students are told to learn a new research method by reading technical literature that assumes they already know this stuff, resulting in stress and frustration.
My Postdoctoral research has focused on understanding the causes and consequences of public misunderstanding about shark fisheries management. While scientists overwhelmingly support sustainable fisheries management as a solution to shark overfishing, many concerned citizens and conservation activists prefer total bans on all shark fishing and trade. Some go so far as to (wrongly) claim that sustainable shark fisheries cannot exist even in theory and do not exist in practice anywhere in the world, and that bans are the only possible solution.
There’s an important piece of data that very rarely makes it into these discussions. Amidst the ongoing discussions about whether or not sustainable shark fisheries are even possible, one right in my backyard became the first shark fishery anywhere in the world to be certified as sustainable by the Marine Stewardship Council.
However, a few years after BC’s spiny dogfish fishery got certified, the certification was quietly withdrawn. I couldn’t find any information in the MSC reports, or in associated scientific literature or government reports, that explained what happened to this fishery, which was thriving until recently. No scientists, managers, or conservation advocates who I asked about this knew exactly what happened to BC’s spiny dogfish fishery.
