An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

Archaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.

Seafloor alkalinity enhancement as a carbon dioxide removal strategy in the Baltic Sea

Communications Earth & Environment
Carbon dioxide removal from the atmosphere and storage over long times scales in terrestrial and marine reservoirs is urgently needed to limit global warming and for sustainable management of the global carbon cycle.

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

The FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

Carbon dioxide removal geoengineering

, 2018
Carbon dioxide removal (CDR) geoengineering, the proposal to counteract anthropogenic climate change by large-scale removal of carbon dioxide from the atmosphere, is playing an increasingly prominent role in the modelling that informs international ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

Journal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Carbon Dioxide Emissions Reductions in New Zealand: A Minimum Disruption Approach [PDF]

Reductions in carbon dioxide emissions can come from (among other things) changes to the structure of final demands, changes in the use of fossil fuels by industry, and changes to the structure of inter-industry transactions.

Method of meal delivery influences estimates of postprandial metabolism and alkaline tide in a benthic fish

Journal of Fish Biology, EarlyView.
Abstract Intragastric gavage is widely used in studies of digestive physiology to deliver standardised meals, yet it remains unclear whether it elicits postprandial metabolic and acid–base responses comparable to voluntary feeding. Here, we tested whether the method of meal delivery affects the magnitude and timing of the postprandial rise in metabolic
