How do you catch the attention of 2,634 isopods? Use the inner-net! Okay, we know, a terrible joke. BUT, a recent article co-authored by Senckenberg Gesellschaft für Naturforschung researchers describes how, through deploying small plankton nets – called “inner nets” – on a recent expedition in the Northwest Pacific, scientists were able to capture over 2,500 isopod specimens! These isopods represent a diverse population, belonging to 14 different families. Read more about the “inner net” technique and the many crustaceans caught on the Hakuho Maru expedition: https://lnkd.in/eNjvABEQ Andreas Kelch Henry Knauber #OceanResearch #MarineResearch #Isopod #Biodiversity #NewPaper Photos: Brandt, A. et al.

#Bioluminescence, or the ability of an organism to create light, is one of nature’s most amazing phenomena. Scientists estimate that 90% of animals living in the #watercolumn are bioluminescent. The #DeepOceanEducationProject hosts a collection of #educationalresources (collected from OET, NOAA Ocean Exploration, and Schmidt Ocean Institute) to learn more about this phenomenon: https://bit.ly/49G3fE5 #TeacherTuesday

If the epitome of fame is having something named after you, #HOVAlvin pilot Bruce Strickrott now has TWO trophies on the shelf: a hydrothermal vent-dwelling hagfish (Eptatretus strickrotti), named in 2005– and as of today, Pectinereis strickrotti, the deep-sea ragworm in this video. Strickrott helped locate and collect the worm while piloting the deep-sea sub around a methane seep offshore of Costa Rica. Researchers from Scripps Institution of Oceanography, #WHOI, and other institutions named the new species after him in a study published today in PLOS ONE. Since 2009, scientists have encountered at least 450 species at the Costa Rican methane seeps, 48 of which are new to science. These impressive stats underscore how much more there is left to learn about these deep-sea ecosystems! Find out more about the latest Strickrott species from Popular Science https://lnkd.in/eHYmfgj3

Ctenophore: Scientists identify jellyfish-like animal as the oldest living creature on Earth.. Scientists in America have discovered the oldest living creature on our planet. It is a jellyfish-like organism called a ctenophore - also known as a comb jelly. They first emerged up to 700 million years ago - a long time before dinosaurs, which only appeared around 230 million years ago. Scientists gradually narrowed the possibilities down to two groups: sponges and comb jellies. Sponges spend their entire adult lives in one spot, filtering food from seawater - while comb jellies swim their way deep down through the world's oceans in search of food. A new study involving researchers from the University of California, Berkeley, has discovered that comb jellies have been around longer than sponges, which date back about 600 million years. https://lnkd.in/gAYatT65

Here's why 6,000 octopuses like to be under the sea at an 'octopus garden'. Off the coast of California is an unusual "octopus garden" — the largest congregation of deep-sea octopuses ever discovered on Earth, where over 6,000 octopuses huddle around an extinct underwater volcano in the black, cold ocean depths, almost two miles below the surface. Most are brooding females that spend their days doing nothing but guarding nests full of eggs, a tedious task which can take nearly two years. It would take even longer if not for the warm water seeping from the seafloor that speeds up the growth of their babies, according to new research that suggests this natural incubator is why octopuses gather there in such huge numbers. https://lnkd.in/dfUEVRPj

I asked Google Gemini ( previously Bard) this question: Can you make a detailed matrix of marine ecosystem impacts of the 2023 and 2024 marine heat wave? Consider the level of heating and based on the best available science, make a matrix with rows and columns with the rows showing the species impacted by the reported levels of heat falling outside the species survivability range, and the column indicating the impact on the species that is dependent on it. Display results in row, column format. For example, if row 1 is plankton and column 1 is blue whale, write in the format (1,1) = plankton, blue whale and describe the likely impact: immediately, in time intervals of 3 months. Do this for the most critical species for a period of 5 years." Gemini didn't make the matrix I asked for but the matrix is still useful.
