Last night, the President of the United States refused to condemn white supremacists terrorist group Proud Boys, called for illegal election interference from his supporters, and threw a variety of tantrums related to his horrifically terrible tenure. Though Climate Change made a small appearance at the debate, unsurprisingly, ocean policy issued were sidelined so that POTUS would have enough time to mock a dead soldier.
Tear gas is bad for fish. Surprising no one, if you unlawfully unload tons of tear gas into a peaceful crowd of protestors in order to create chaos as a precedent for state violence, that tear gas will eventually find its way into drains and all drains lead to the ocean. And that is bad news for marine life.
When you live in the darkness of the abyss, finding a partner is hard and keeping a partner is even harder. Deep-sea anglerfish, one of the iconic ambassador species of the deep ocean, have found a novel solution to this problem–dwarf males are sexual parasites that latch onto the body of the much larger female anglerfish and then physically fuse to their partner, becoming permanently attached to the point where they share a circulatory and digestive system.
Parasitic dwarf males are uncommon, but not unheard of, throughout the animal kingdom. Osedax, the deep sea bone eating worm, also maintains a harem of dwarf males in a specialized chamber in their trunk. But few species, and no other vertebrates, go to quite the extremes of the anglerfish. And with good reason.
Vertebrate immune systems have a long shared history. The Major Histocompatibility Complex (MHC) is a suite of genes shared among all gnathostomes–the taxonomic group that contains all jawed vertebrates, from fish to fishermen. It creates the proteins which provide the foundation for the adaptive immune system, the core complex which allows bodies to tell self from no-self, detect pathogens, and reject non-self invaders. Suppressing the MHC seriously inhibits a vertebrate’s ability to fight off infection.
Incidentally, not all deep-sea anglerfish have parasitic dwarf males, and the species most often presented as a type specimen in the popular press, the humpback anglerfish Melanocetus johnsonii, is one of several that do not have permanently attached parasitic dwarf males. M. johnsonii males are free-swimming throughout their life, they’re just small and clingy.
There are currently 5 active tropical cyclones in the Atlantic.This has only ever been documented once before. Historically, we are just entering the most active part of the Atlantic Hurricane season and it’s already time to move on to Greek letters. The next earliest 20th named storm was Tropical Storm Tammy, which formed October 5, 2005.
Killer whales are attacking boats in the Mediterranean.Ok, then.
Frisky business for Great White Sharks. For only the second time since western scientists began studying the ocean, Great White Shark mating has been documented in the wild. Shark sex is infrequently observed in the wild, and this fisherman’s observations can provide invaluable insight in the lives and loves of this iconic species.

For over 50 years, deep-ocean explorers have been able to claim that more people have walked on the moon than have dived to the deepest point on the Earth. Only two men descended into Challenger Deep in the 20th century–Don Walsh and Jacques Piccard–they were joined in the early 2010s by director James Cameron. Earlier this year, Victor Vescovo became the fourth to reach the bottom of Challenger Deep and, over the course of several subsequent dives this summer, the ranks of those who’ve reached the deepest ocean has swelled.
Astronaut, oceanographer, and former NOAA Administrator Kathy Sullivan and explorer and mountaineer Vanessa O’Brien became the first and second woman to dive to the bottom of Challenge Deep aboard the privately owned HOV Limiting Factor, piloted by Vescovo and his team.
The disaster continues in Mauritius. With the cleanup and salvage well underway, Mauritius has begun assessing the broader impacts of the disastrous bulk carrier wreck. Fishermen have reported seeing 30 to 30 dead dolphins floating in a lagoon near the wreckage including mothers and calfs. Dead whales, as well as sick and injured whales, are also being recovered close to the site of the spill.
All hail the Calamari Comeback State. Why is Rhode Island the Calamari Comeback state? Climate change and overfishing. Squid are moving north into Rhode Island’s waters and all their other major seafood products are becoming increasingly depleted due to overfishing and environmental degradation. What a comeback!
Upwelling (the part where Andrew gets on his soapbox)
Sometimes, the current POTUS will go off on a weird nonsense ramble about a topic your have expertise in. There is a huge, natural desire to contextualize those statements and find the nuggets of reality in them.
This is competence laundering.
I’m guilty of it too. It’s so hard to resist talking about the Outer Continental Shelf Lands Act when the President says we should buy Greenland. I was more vigilant during yesterday’s shark nonsense. Trying to contextualize what he’s really talking about is to ascribe a level of understanding to a topic that he clearly does not have.
Maybe he saw a thing about great whites on Fox News. Maybe he got a briefing about seal and salmon conflict in the Pacific Northwest. Or maybe he saw the Shark Week Mike Tyson Special and can’t tell the difference between the heavyweight champion of the world and the man who sung Kiss from a Rose because he’s an unrepentant racist.
You don’t know which it is. Trying to contextualize the inane ramblings of an incurious man does nothing but obscure the profound incompetence. It’s competence laundering. We don’t have to be complicit. The answer to what the heck he was talking about [last week] is “I don’t know and he doesn’t either.”
Politics aside, just watch the amazing Roll Call Across America from last night’s Democratic National Convention. An absolutely amazing tour of the 50 states and seven territories of the United States.
Our world is in turmoil. From the chaos rises a new breed of academics, dedicated to the proposition that, amidst the fire and fury, with the seas rising around us and pandemics descending upon our communities, they alone have the foresight to lead you into the light, to guide you towards a greater good, to brace the walls and cry out, with clarity of purpose, “No More!” They will raise a clarion against that greatest of tribulations: looking sloppy while teaching on Zoom.
I get it. It’s frustrating right now. We’re all trying to figure out how to be good educators and mentors and colleagues in a new, uncertain semester of hybrid classes, asymmetric learning, and teaching from a home that perhaps reveals a little too much about the grim prospects of academia to our bright eyed students. There are ways to make it better, and there are faux pas to avoid but no one has any idea what “professionalism” looks like in the age of Zoom.
This is new ground. We are the professionals. Whatever we need to do to make the class work, provide our students with an enriching and valuable education experience, and not collapse, exhausted, into a three-week-old laundry pile where we lie, like a barnacle, until the next lecture, is professional.
But given all that, there are a few things you can do to improve the teach-from-home experience for you and for your students.
