A groundbreaking new database catalogs the body sizes of marine animals, creating a vast "library of life" 🌊🐋. This resource will help scientists better understand ocean biodiversity and the impacts of climate change.

Ars Technica · New body size database for marine animals is a “library of life”Von Jennifer Ouellette
Brad Rosenheim

Freezing a CO2 sample into a glass ampoule with titanium hydride and zinc hydride, with another ampoule inside that contains iron. This is done with liquid nitrogen in a styrofoam cup because we have to seal the ampoule with flame and these cups can be sacrificial if torchwork is sloppy.

We later heat these ampoules up to a point when hydrogen gas is produced by the hydrides. The hydrogen and carbon dioxide gases bounce molecularly around the chamber and when both molecules find themselves in proximity of the iron surface at the same time, they form water and graphite (solid). The end result is graphite that can be packed into an aluminum cathode (with the iron) and ultimately sputtered with a cesium ion beam in vacuum to form a negative carbon ion beam that is accelerated through a mass spectrometer to count the ration of 14C to 12C (radiocarbon dating).

The original sample here was mangrove peat, which are measuring to determine the ability of mangroves to pump atmospheric CO2 down to deeper depths of mangrove peat.

The post highlights a major imbalance in global ocean research, heavily centered in East Asia, and urges international policymakers to invest in underserved regions. It calls for inclusive, cross-border marine research to advance SDG 14 and ensure equitable, global ocean governance for a sustainable blue future.

It may not look like much, but the light coloring on this little piece of filter paper is around 2 billion marine bacteria. While I've been out sailing along Line P, I'm trapping bacteria on these slips of paper by pumping water through the tiny little holes in the paper that are smaller than the bacteria but large enough for water to slip through. Once I get these to the lab, I can pop the bacteria open to collect their DNA and see who lives in the water and what they can do.
