Climate change and underwater light: Large‐scale changes in ultraviolet radiation transparency associated with intensifying wet–dry cycles

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Ultraviolet radiation (UV) is the most energetic waveband of incident solar radiation and has wide‐ranging effects in the aquatic environment. Our analysis of an 18‐year record of underwater irradiance and related limnological variables in sub‐alpine, ultra‐oligotrophic Lake Tahoe revealed orders of magnitude changes in UV transparency ...

The deep ocean as a major sink for terrestrial organic carbon

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Rivers transport ~200 Tg of particulate organic carbon (POC) to the global ocean annually, of which 30% is known to be buried in continental‐shelf sediments. The fate of the remaining “missing” terrestrial POC (POCterr) remains uncertain, with proposed explanations including rapid remineralization or transport to the remote deep ocean.

Aquatic heatwaves increase surface chlorophyll concentrations in experimental and reference lakes

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Aquatic heatwaves are increasing in frequency, intensity, and duration worldwide. While increases in mean water temperatures are linked to enhanced phytoplankton biomass, it is unclear how heatwaves alter phytoplankton dynamics in lakes at an ecosystem scale.

Recognition of Harmful Phytoplankton from Microscopic Images using Deep Learning [PDF]

open access: yesarXiv
Monitoring plankton distribution, particularly harmful phytoplankton, is vital for preserving aquatic ecosystems, regulating the global climate, and ensuring environmental protection. Traditional methods for monitoring are often time-consuming, expensive, error-prone, and unsuitable for large-scale applications, highlighting the need for accurate and ...

Using the diel cycle of ocean microbes to better understand their biogeochemical functions

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract The daily cycle of solar radiation has a profound influence in structuring the physiology of microbes in the euphotic zone and subsequently setting the degree of coupling across trophic levels within ocean ecosystems. There has been an upsurge of interest in the biological role of the diel cycle and the ability to probe it using molecular ...
