A Closer Look at a Tiny, Floating Horde

sea_urchin_larvae_kirby_ocean_drifters

It’s a strange but true fact that the young of many familiar sea creatures look nothing like them. Drifting on currents to distribute their kind, they are an unsung part of the plankton, itself an unsung part of the sea. A few years back, I wrote about the work of Richard Kirby, a research fellow [...]

vampiroteuthis_infernalis_screenshot_200

Waters nearly devoid of oxygen are not just found off the coast of South America, as we saw last time. “Oxygen minimum zones” may occur throughout the world’s ocean’s at mid-water depths where food consumption is high but supplies of oxygen are low. Although, as I mentioned last time, such waters are dead zones for [...]

Missing Nitrogen May Be Vanishing in the Tubes of Giant Bacteria

Off the coast of Mexico’s Baja Peninsula lies a dark, still, deep place. It is called the Soledad Basin, and in it lies a garden of bacteria so large you can see them with your own eyes. A 250-m high ridge on the edge of the Soledad basin traps water inside. No strong currents disturb [...]

The Private Life of Plankton — in HD

ceratium_plankton_chronicles

Artistic black-and-white photos of plankton — as we saw last time — are fabulous. But what if one hungers for HD? The Plankton Chronicles have got you covered. On Friday I wrote about the Plankton Portal, a project to enlist the public’s help in identifying and cataloguing weird, deep-sea life. Via their blog, I learned [...]

If you’re like me, you’ve pondered from time to time the goings-on of life in the deep. What’s happening down there this very moment? What do the creatures look like when they’re just hanging out? But most of us will never be able to take a trip in a submersible. Now, though fuzzy and in [...]

Wonderful Things: The Universe Between the Sand Grains

gastrotrich_Thaumastoderma_ramuliferum_wiki_cc_Todaro_et_al_200

This is the fourth post in the Wonderful Things series. As we saw last time, the thin strip of sand found on beaches is home to many organisms that can dwell no where else. But the strip swept by waves — the intertidal — may be the richest part of all. Living between the wet [...]

Glass Sponges Poriferify — and Beautify — Impoverished Antarctic Neighborhood

glass_sponges_Larsen_Fillenger_et_al_200

Glass sponges are taking over a newly sunlit strip of Antarctic marine real estate at a blistering clip, surprising biologists who had no idea they had it in them. And what’s in them, it turns out, is also fairly astounding. The story, as was widely reported last month, is this: Although more than 30% of [...]

The Swimming Sea Cucumber and the Exploding Paint Pack

Sea cucumbers aren’t all boring, trundling bags. Some of them swim — and glow. Though I opted to focus on creatures found at greater depths in my last post, one of the creatures observed by the Deepsea Challenger expedition in the New Britain Trench at a relatively shallow 1000 meters was just such a swimming [...]

What Lives at the Bottom of the Mariana Trench? More Than You Might Think

foraminiferan_ammonia_tepida_wiki_cc_Scott_Fay_200

The deepest, darkest, scariest place on the maps I loved pondering as a child was a crescent-shaped canyon in the western Pacific Ocean. It was called the Mariana Trench, and at the very, very bottom was the lowest point on Earth’s surface, the Challenger Deep. Its floor was seven terrifying miles down. What was down [...]

Cameron’s Team Divulges Discoveries in Deepest Trenches on Earth

xenophyophore_noaa_pd_200

It’s often said that we know less about the bottom of our own ocean than we do about the surface of Mars. The governments of the world, and our government in particular, seem presently much less than enthusiastic about exploring the oceans of our own planet than in exploring other planets (ocean research seems to [...]
