Bigg, who has studied how large icebergs have <a href=\"https:\/\/doi.org\/10.1038\/ngeo2633\" rel=\"noopener\">enhanced phytoplankton activity<\/a> in this region, noted that while blooms unconnected to icebergs do occur regularly here, satellite imagery shows a connection that has persisted for weeks\u2014increasing his confidence that the iceberg and phytoplankton bloom are related.<\/p>\n<p>The primary factors that limit phytoplankton in this region are access to light and nutrients, explained Heidi Dierssen, an oceanographer at the University of Connecticut. Light can be limiting even in the summer because phytoplankton are often mixed too deeply in the water column due to high winds and turbulence.<\/p>\n<p>Melting icebergs can boost phytoplankton by both creating a stable surface layer with favorable growth conditions and releasing plumes of meltwater rich in iron\u2014a key nutrient for phytoplankton that can be scarce in this part of the South Atlantic, she said. <a href=\"https:\/\/doi.org\/10.5194\/tc-18-5735-2024\" rel=\"noopener\">Research<\/a> indicates that icebergs also often contain significant amounts of manganese and macronutrients, such as nitrates and phosphates, that can benefit phytoplankton. These nutrients often accumulate on icebergs through windblown dust or through contact with bedrock or soil.<\/p>\n<p>The <a href=\"https:\/\/science.nasa.gov\/mission\/landsat-8\/\" rel=\"noopener\">Landsat 8<\/a> image above, captured by the <a href=\"https:\/\/science.nasa.gov\/mission\/landsat\/oli\/\" rel=\"noopener\">OLI<\/a> (Operational Land Imager) on January 25, 2026, shows blue meltwater pooling on several of the larger fragments. The linear patterns are likely related to\u00a0<a href=\"https:\/\/serc.carleton.edu\/vignettes\/collection\/68528.html\" rel=\"noopener\">striations<\/a>\u00a0that were etched hundreds of years ago when the ice was part of a glacier moving across Antarctic bedrock. Brown staining, perhaps soil or sediment, is visible on some of the bergs.<\/p>\n<p>Bigg also noted that the phytoplankton signal appears to be more concentrated near the smaller bergs, possibly because these are melting faster, releasing nutrient-rich material at a higher rate. Dierssen added that it\u2019s also possible that chlorophyll concentrations may be higher near the largest bergs than they appear because algorithms sometimes overcorrect for <a href=\"https:\/\/doi.org\/10.1002\/lol2.70043\" rel=\"noopener\">\u201cadjacency effects\u201d<\/a> near bright surfaces, like ice, when processing chlorophyll data.<\/p>\n<p>Ivona Cetini\u0107, a researcher on NASA\u2019s <a href=\"https:\/\/pace.oceansciences.org\/project_science_team.htm\" rel=\"noopener\">PACE science team<\/a>, checked a database for clues about the smallest, or \u201cpico,\u201d phytoplankton swirling around the bergs.

The PACE team is currently developing additional tools that will help identify communities of larger types of phytoplankton, which were likely present as well.<\/p>\n<p>Some <a href=\"https:\/\/doi.org\/10.1038\/ngeo2633\" rel=\"noopener\">research<\/a> suggests that icebergs may have contributed significantly to phytoplankton blooms in this region in recent years, possibly accounting for up to one-fifth of the Southern Ocean\u2019s total <a href=\"https:\/\/www.usgs.gov\/faqs\/what-carbon-sequestration\" rel=\"noopener\">carbon sequestration<\/a>. Other research teams have concluded that surface waters trailing icebergs were about <a href=\"https:\/\/doi.org\/10.1016\/j.dsr.2009.05.003\" rel=\"noopener\">one-third more likely<\/a> to have increased amounts of phytoplankton compared to background levels. \u00a0<\/p>\n<p>How long iceberg A-23A will enhance phytoplankton productivity before and after disintegrating completely remains an open question.
