The determination of par levels from absorption coefficient profiles at 490 nm

Ciencias Marinas, 1999
A model is presented that allows the prediction of percent photosynthetically available radiation (PAR) levels from measured profiles of the absorption coefficient at 490 nm in the Gulf of California. Percent PAR levels depend on the diffuse attenuation

Dendrite Formation and Self‐Healing Mechanism in Ionic Liquid‐Based Magnesium Batteries

Advanced Energy Materials, EarlyView.
This graphical illustration highlights the importance of operating Mg batteries within a safe operating current density (SOCD) range. Beyond this range, Mg batteries are susceptible to dendrite formation. However, when cycling a dendritic cell with a highly thermally stable electrolyte, a self‐heating effect occurs.

Upper-ocean circulation patterns in the northern Gulf of California, expressed in Ers-2 Synthetic Aperture Radar Imagery

Ciencias Marinas, 2001
ERS-2 Synthetic Aperture Radar (SAR) frames were collected over the northern Gulf of California during winter 1999. The frames, presented here as a single composite image (100 x 300 km), express a mesoscale meander or eddy-like feature, approximately 80

Spatio-temporal patterns of beaked whale echolocation signals in the North Pacific. [PDF]

, 2014
At least ten species of beaked whales inhabit the North Pacific, but little is known about their abundance, ecology, and behavior, as they are elusive and difficult to distinguish visually at sea.

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

Advanced Energy Materials, EarlyView.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Evidence of different stocks of mackerel Scomber japonicus

Ciencias Marinas, 1996
Samples of the commercial catch of mackerel Scomber japonicus from Ensenada, Vizcaíno Bay, Magdalena Bay and the Gulf of California were analyzed to show biological evidence that supports a hypothesis of two stocks of mackerel.

Migrations of yellowfin and skipjack tuna in the Eastern Pacific Ocean as determined by tagging experiments, 1952-1964 [PDF]

, 1970
ENGLISH: Totals of 59,547 tagged yellowfin and 90,412 tagged skipjack were released during 1952-1964 throughout the range of the fishery in the eastern Pacific Ocean during that period.

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.
