Hurricanes, Sharks, Mining the Deep Sea, and the Great American Outdoors – What’s up with the Ocean this week?

August 5, 2020

Holy Mola we are back! Bass my flounder for I have finned. It has been Half A Year since I last posted anything on Southern Fried Science. Granted, that year is 2020, so I think we can all give each other all the slack we need. I have missed this place, my weekly ocean news round ups, and my less frequent deep dives into ocean science, conservation, and exploration. So let’s get back to it: What the heck is up with the ocean this week?

Hurricane Isaias. Hurricane Isaias ripped across the eastern seaboard, striking the Bahamas as a category 1 hurricane before slowing as it approached the United States. It briefly ramped back up to a category 1 storm as it strafed the North Carolina coastline. Isaias spun off hundreds of tornadoes as far north as Delaware as it crawled towards Maine and the Canadian Maritimes. It is the ninth named storm of 2020, the earliest ninth storm to form on record, and the second consecutive hurricane of the season. 2020 is projected to be an exceptionally intense year for Atlantic hurricanes, because of course it is.

Woman killed by Great White Shark. A woman was killed by a Great White Shark last week in Maine’s first recorded lethal shark encounter. Though Great Whites are uncommon, they are not unheard of in northern waters and the recovery of shark populations in the north Atlantic is in general regarded as a success story. With rebounding populations, interactions between humans and wildlife will increase, although such tragic outcomes are still rare. In a strange twist, the victim in this case was an acquaintance of our own resident shark specialist

We still don’t know how to assess the impacts of deep-sea mining. In Deep-Sea Misconceptions Cause Underestimation of Seabed-Mining Impacts, Smith and friends outline the numerous potential misconceptions that may dramatically affect our estimations of the impact of deep-sea mining. These misconceptions include the scale of the operation, the rate of recovery, and the compounding impacts of other human-induced insults to the seafloor. 

Upwelling (the part where Andrew gets on his soapbox)

Yesterday, the President signed the Great American Outdoors Act, a largely bipartisan effort to dramatically increase funding for land conservation across the US; an act that was necessary following decades of Republican leadership gutting funding for the National Parks Service and deferring essential repairs. The $9 billion in funding for deferred maintenance will go towards offsetting over $12 billion in critical repairs that have accumulated since the 1980s, the last decade in which the Park Service budget was significantly increased. It also guarantees almost $1 billion per year for the Land and Water Conservation Fund, which is predominantly funded though royalty payments from offshore oil and gas. 

It’s a great law made necessary by decades of leadership failure. 

Saltiness aside, it comes at a time when access to the outdoors could not be more essential. With the country in the midst of an historic pandemic and travel significantly curtailed, access to green space is at a premium. And, unsurprisingly, nature deficit disproportionately affects historically marginalized communities, particularly those within urban areas where vast green spaces come in the form of literal walled gardens. 

Even with the Great American Outdoors Act, this administration has done more to destroy the environment than any modern presidency, and we can only hope that this will help lay the groundwork for the next president’s Green (and Blue) Awakening.

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.

Bioshock Oceanographic: How deep is Rapture?

“To build a city at the bottom of the sea! Insanity. But where else could we be free from the clutching hand of the Parasites? Where else could we build an economy that they would not try to control, a society that they would not try to destroy? It was not impossible to build Rapture at the bottom of the sea. It was impossible to build it anywhere else.”

Andrew Ryan, Bioshock

Rapture, a city beneath the sea, the crowning achievement of Randian industrialist Andrew Ryan. This atmospheric world of technological wonder and urban decay serves as the setting for one of the greatest video games of all time, Bioshock. The player, finding themselves stranded at sea in a fiery plane crash, makes their way towards a lonely lighthouse, descends into the sunken, desolate city, and unlocks the mysteries surrounding the creation and destruction of a most unusual city.

Rapture. From Bioshock.

Rapture. From Bioshock.

Though many questions are answered as the player journeys into the heart of Rapture, collecting audio diaries of its residents along the way, one question still eludes: How deep is Rapture and where, exactly, is it?

What Jaws Teaches Us About Scientists and the Future of Shark Bite Politics

neffDr. Christopher Neff is a Lecturer in Public Policy in the Department of Government at the University of Sydney. He completed the first PhD on the “Politics of Shark Attacks” and has been published in Marine Policy, Coastal Management and the Journal of Homosexuality. 

Jaws is a great horror movie. Personally, it’s one of my favorites. Politically, it kills me. While it has certainly inspired generations of marine biologists, researchers and social scientists (like me) since its release in 1975, it has also served as the most powerful vehicle to advance public fear of sharks in modern history. These two different implications become problematic because while sharks make for great movies, movies make for lousy public policy. When tragic shark bite incidents occur, there is a classic Jaws-esque analogy just waiting to be made. And sometimes the media circus turns into policy.

I recently wrote an article called “The Jaws Effect” for the Australian Journal of Political Science comparing policymaking in Western Australia and the movie Jaws. While, we see some of these comparisons in real-time the reason it is important to study this formally is because these moments can tell us about the tensions between politicians and scientists that lead to myth-based policies.

Agents of seal: stealthy seals use subsurface structures to sneak by sharks

Predators are highly influential in ecosystems because of the many top-down effects they can have.  The most obvious and direct way predators influence an ecosystem is by eating and reducing the number of prey animals in the system, but another equally important way is the indirect influence they have on the behaviour of prey animals.

If you have avoided parking on a risky-looking street, taken a different route between classes to avoid a bully, or abandoned a forest hike because of snapping twigs in the distance, you have been indirectly affected by perceived ‘predators’.  In the wild, prey animals will also change their behaviour when they perceive that predators are around, and these altered behaviours often influence other species, ultimately shaping the ecosystem.

Great white shark movements at Geyser Rock

michelleMichelle Wcisel is a Zoologist specialized in predator/prey behaivour and the Scientific Communicator for EDNA Interactive.  She has spent the past 4 years studying the behaviour of white sharks and Cape fur seals at Geyser Rock, ‘Shark Alley’, South Africa.  

 

Animal movement is often shaped by natural barriers; a fish can’t leave the river it swims in, a tortoise is going to struggle to climb a cliff face, and a pangolin can’t swim across the sea.  These barriers come quite naturally to the animals, yet researchers have often struggled to account for these constraints in movement analysis, particularly when it comes to estimating home range (or ‘Utilization Distributions’, UDs).  Unfortunately, the few solutions that have attempted to account for barriers are often incredibly complicated without providing much improvement overall, so previous studies have been forced to simply ‘clip out’ the parts of the estimate that extend over these inconceivable areas (i.e. Heupel et al. 2004; Hammerschlag et al. 2012; Jewell et al. 2012).

3 sharks that were on twitter before being a shark on twitter was cool

Recent plans in Western Australia to place acoustic tags in sharks and have them tweet their location when they approach a beach have resulted in a sharknado of media coverage. The plan has been covered by internet technology news giant Mashable, Fox News, NPR news, Popular Science, and NBC news (which, with “sharks with frickin’ tweets,” has what I believe to be the best headline. That one also interviews me.) When a tagged shark approaches the beach, a tweet like this results:

I can understand why a project involving both sharks and twitter caught the media’s eye… and why about a billion of you e-mailed or tweeted the news to me. However, these aren’t the first sharks to be on twitter!
