#WeekendReading: Cole et al., on the weird and strange relationships between Mg/Ca ratio in #seawater and echinoderm #evolution.

Warning: study includes and describes animal experimentation.

Experimental design and results of ophiuroid (Ophioderma cinerum) regeneration experiments. (A) Schematic of the experimental setup, timeline, and data collection. (B) Regenerated arm growth as a function of time for each seawater Mg/Ca treatment; solid points represent mean regenerated arm length for treatments, crosses are measurements for all specimens. (C) Bar plot of estimated β coefficients from a linear regression analysis of arm growth through time, revealing that all treatments have statistically different growth rates; error bars represent 95% confidence intervals.

Seawater is an electrolyte, that is why we can use cathodic protection for metals we submerge in it. But it also means we can make #batteries with seawater... assuming we can overcome the many, many complications related to the complex ionic mix that is #seawater.

We have a new paper!
Led by Maxim Rubin-Blum, we show the role #burrows and burrowing #animals have on in cold seeps.
Burrowing doesn't just mix sediment, it opens conduits that connect #seawater rich in NOx and sulfate to a subsurface domain rich in organic matter but poor in oxidizers. Fueling biological reactions and interacting as well as, potentially, things like diagenetic calcification.

maps and chart - Spatial map of southern Weddell Sea with summer (DJF) climatology and anomalies for sea ice concentration (SIC; a–d), zonal wind (e–h), and ocean surface stress curl (i–l).

Overview map of the Filchner Trough region in the eastern part of the southern continental shelf in the Weddell Sea. The bathymetry is from IBCSO (Arndt et al., 2013) with marked contours every 100 m. Grounded ice is shaded dark gray and floating ice shelves are light gray. Mooring locations are marked with colored circles, historic CTD casts with gray dots, and the deployment location of the APEX floats as diamonds. Red and blue arrows are a sketch of the circulation of relevant water masses, mWDW and ISW, respectively. The inset in the upper left shows the location of the study site.

maps and charts:
(a) Velocities from the moorings averaged within 0.1°C temperature bins
(b) Temperature (according to colorbar) along the float trajectories of Fst (brown diamond, through the Small Trough), Fsill (green diamond, along the eastern flank), and Fcs (purple diamond, within the Filchner Trough) at their parking depths of 400, 400, and 250 metres, respectively.
(histograms) temperature bins within the temperature ranges of ISW and mWDW.

photo - It used to be that researchers didn't study what happens in the Arctic during the polar night because it was difficult to work there. But over the past decade, researchers have ventured into this environment and have come up with surprising findings. Norway's research-dedicated icebreaker, Kronprins Håkon, launched in 2017, is an important tool for this research. Photo: Robin Hjertenes

Sea urchin larvae can get nutrition from molecules dissolved in seawater https://oceanbites.org/whats-on-your-plate/

Integrative biological analyses of responses to food deprivation reveal resilience mechanisms in #SeaUrchin larvae https://onlinelibrary.wiley.com/doi/10.1111/mec.17120

"these #larvae feed on dissolved organic matter — basically just any of the organic goop found in #seawater... This way, even when regular food is unavailable, #SeaUrchins can gain sufficient energy from molecules in the seawater itself. The sea is soup."

the #seawater #greenhouse is a really cool idea, literally. It's a way of using evaporating seawater to cool and humidify crops , which can drastically reduce the amount of fresh #water needed to support the #crop in a desert #climate.

As #climatechange and #freshwater scarcity increasingly challenges crop survival over the coming decades, carbon neutral seawater greenhouses will become much more common.
