Phytoplankton blooms of the coccolithophore E. huxleyi are known to produce CO 2 , causing less uptake of atmospheric CO 2 by the ocean, but a global assessment of this phenomenon has so far not been quantified. Therefore here we quantify the increase in CO 2 partial pressure (Δ p CO ...
Phytoplankton blooms south of Vancouver Island. Satellite image: NOAA-20, July 26, 2023, public domain. Toxic blooms The presence of a phytoplankton bloom isn’t always benign. Some can be harmful algal blooms (HABs), where certain species produce toxins that can harm marine life and even pos...
Satellite image of a striking phytoplankton bloom in the North Atlantic captured on June 16, 2024, by the Moderate Resolution Imaging Spectroradiometer on NASA’s Aqua satellite. A short-lived gap in the clouds let satellites observe a stunning phytoplankton bloom east of Greenland. Satellite...
Given adequate sunlight and nutrients, phytoplankton populations can multiply into blooms large enough to be visible from space. On the morning of May 18, 2021, the Moderate Resolution Imaging Spectroradiometer (MODIS) onNASA’s Terra satellite acquired this natural-color image of a phytoplankton bloo...
We generated a satellite-based dataset of phytoplankton bloom occurrence to characterize the spatial and temporal patterns of algal blooms in coastal oceans globally. The dataset was derived using global, 1-km resolution daily observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on...
Southern Oceanphytoplankton bloomArgoSOCCOMSOCLIMThe spring bloom in the Southern Ocean is the rapid-growth phase of the seasonal cycle in phytoplankton. Many previous studies have characterized the spring bloom using chlorophyll estimates from satellite ocean color observations. Assumptions regarding the ...
In this study, we investigated the seasonal and interannual variability and long-term changes in phytoplankton blooms in the eastern China seas using a 14 yr (1998???2011) time series of satellite ocean colour data. To ensure a proper satellite dataset to figure out the bloom events, we ...
These observations, coupled with additional biogeochemical evidence, suggest that phytoplankton blooms are currently widespread on nutrient-rich Arctic continental shelves and that satellite-based estimates of annual primary production in waters where under-ice blooms develop are ~10-fold too low. These ...
Phytoplankton blooms in coastal oceans can be beneficial to coastal fisheries production and ecosystem function, but can also cause major environmental problems1,2—yet detailed characterizations of bloom incidence and distribution are not available worl
Using satellite data from the Landsat 5 Thematic Mapper (L5TM), Ho et al.1 showed an increase in peak summertime bloom intensity in 68% of the 71 large lakes worldwide from 1982 to 2012. However, we question the veracity of their finding for at least two reasons: (1) satellite-derived...
