Variability of Acoustically Evidenced Methane Bubble Emissions Offshore Western Svalbard

Geophysical Research Letters, 2019
Large reservoirs of methane present in Arctic marine sediments are susceptible to rapid warming, promoting increasing methane emissions. Gas bubbles in the water column can be detected, and flow rates can be quantified using hydroacoustic survey methods,

Spatio-Temporal Variability of Chlorophyll-A and Environmental Variables in the Panama Bight [PDF]

Remote Sensing, 2020
The analysis of synoptic satellite data of total chlorophyll-a (Chl-a) and the environmental drivers that influence nutrient and light availability for phytoplankton growth allows us to understand the spatio-temporal variability of phytoplankton biomass.

Temporal Variability of Gallium in Natural Plants

Toxics, 2023
The aim of the research was to study the distribution of gallium (Ga) in rhizosphere soil and in plants growing under natural conditions in uncontaminated sites, with an emphasis on temporal fluctuations of Ga concentration in plants. For this purpose, two field experiments were conducted in St. Petersburg, Russia, in 2019 and 2020, at two sites. Three
