Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, EarlyView.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Measurement and modeling of diffuse ultraviolet radiation: A review

Photochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.

Oceanographic conditions in the Coquimbo upwelling system during the year 2023

A series of discrete measurements were obtained on a near-monthly basis in a subtropical upwelling area of the Humboldt Current System during the year 2023. These included temperature, salinity, dissolved oxygen, fluorescence, and pH profiles, as well as

A review of ecological risks of coral reef interventions

Restoration Ecology, EarlyView.
Abstract Introduction Coral reefs, essential for biodiversity, livelihoods, and global economies, face severe threats from climate change and other stressors. Curbing greenhouse emissions is crucial, but the urgent situation also calls for immediate intervention strategies.

Modelling upwelling

, 2020
Upwelling is a process in which cold water, rich in nutrients and small fish, rises towards the surface. Some countries of the Global South have based their economy on this godsend, for better or for worse… As these areas are temperamental and sensitive to climate variability.

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

Sedimentology, EarlyView.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Diverse Responses of Upper Ocean Temperatures to Chlorophyll‐Induced Solar Absorption Across Different Coastal Upwelling Regions

Geophysical Research Letters
Chlorophyll in phytoplankton absorbs solar radiation (SR) and affects the thermal structure and dynamics within upwelling regions. However, research on this process across global‐scale coastal upwelling systems is still lacking.

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, EarlyView.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.
