Two decades of satellite data show that narrow ocean fronts—where water masses meet—are hotspots for carbon capture due to vertical mixing and phytoplankton blooms. These small zones disproportionately absorb CO₂, suggesting climate models may underestimate ocean carbon storage if they ignore front dynamics; incorporating them could improve predictions of the carbon cycle.
Samsung today announced the global launch of the 13-inch Color E-Paper (EM13DX), the world’s first commercial display with a phytoplankton-based bio-resin housing. The ultra-thin, 1,600×1,200 color panel runs on ultra-low power (static images at zero watts) and uses a rechargeable battery, USB-C, and flexible mounting, while its housing uses 45% recycled plastic and 10% bio-resin, cutting carbon emissions by more than 40% versus petroleum plastics; packaging is 100% paper. Content is managed via the Samsung E-Paper App or Samsung VXT, with a 20-inch model to follow at ISE 2026 as Samsung expands its digital signage lineup.
NASA's VIIRS satellite captured a ring-shaped phytoplankton bloom around the Chatham Islands, where nutrient-rich upwelling from the Chatham Rise and the clash of cold Antarctic and warmer subtropical waters fuel rapid algae growth. The vivid greens and blues reveal a seasonal, highly productive marine ecosystem that supports fisheries and marine mammals, though the area is also known for mass strandings tied to its complex oceanography.
NASA's Earth Observatory captured a vibrant ring of phytoplankton encircling the remote Chatham Islands in January 2026, observed by the VIIRS instrument on NOAA-20. The bloom forms where cold, nutrient-rich Antarctic waters meet warmer subtropical waters around the Chatham Rise, supporting local fisheries and marine life, though the region is also known for whale and dolphin strandings.
Future ocean warming is predicted to cause a significant decline in Prochlorococcus biomass and productivity beyond a temperature threshold of approximately 28°C, which could lead to cascading effects on marine food webs and carbon cycling, despite some potential for adaptation.
Oceanographers have discovered that the bright turquoise patch in the Southern Ocean, previously thought to be caused by coccolithophores, is actually due to dense populations of diatoms, challenging previous assumptions about microorganism distribution and their role in the carbon cycle in cold waters.
A study published in Nature Climate Change reveals significant shifts in Antarctic phytoplankton communities over nearly three decades, driven by reduced sea ice and iron availability, leading to a decline in diatoms crucial for carbon sequestration. These changes threaten to disrupt the marine food web and accelerate global climate change by decreasing the ocean's ability to store carbon, highlighting the importance of long-term data collection in understanding climate impacts.
NASA-supported research using supercomputers has revealed that melting glaciers in Greenland, particularly the Jakobshavn Glacier, are releasing nutrients that boost phytoplankton growth, which could impact marine food webs and carbon cycling, with broader implications for understanding climate change effects on ocean ecosystems worldwide.
NASA-supported research using supercomputers and advanced ocean models has shown that melting glaciers in Greenland release nutrients that significantly boost phytoplankton growth, impacting the Arctic ecosystem and carbon cycle, with potential implications for marine life and climate change.
A two-decade satellite study reveals significant shifts in ocean color, with high-latitude regions greening and tropical waters losing productivity, indicating a climate-driven reorganization of marine ecosystems that could impact carbon storage and fisheries.
Warming waters are causing ocean colors to shift, with polar regions greening due to increased chlorophyll from phytoplankton, potentially impacting marine food webs and fisheries, though climate change is not the sole factor.
Over the past 20 years, more than half of the world's oceans have changed color, a shift linked to human-driven climate change affecting phytoplankton communities. These microscopic organisms are crucial for marine ecosystems and carbon capture. The changes, observed via satellite data, indicate significant impacts on the marine food web and highlight the urgent need to address climate change.
NASA is set to launch the PACE satellite on Feb. 6 to monitor Earth's oceans, atmosphere, and land from space. The mission aims to study phytoplankton dynamics in the ocean, track aerosols and clouds in the atmosphere, and observe land vegetation stress. PACE will provide valuable insights into marine ecosystem health, air quality, and climate change impacts, offering a comprehensive view of our planet's health from space.
The warming Arctic climate has triggered a radical ecosystem shift in Great Slave Lake, North America's deepest lake. The microscopic algae, or phytoplankton, at the base of the lake's food web have undergone a regime change, with larger diatoms being replaced by smaller, pancake-shaped counterparts. This shift could impact the lake's productivity, carbon dynamics, and food web, affecting nearby communities that rely on the lake as a food and cultural resource. The transformation is attributed to rising temperatures, declining ice cover, and slowing winds in the region. Similar changes are also observed in Great Bear Lake.
A new study explores the relationship between phytoplankton physiology and global climate. Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle. Variations in phytoplankton physiology, particularly nutrient uptake, can impact the chemical composition of the ocean and atmosphere, potentially affecting global climate. The study emphasizes the importance of variable stoichiometry of phytoplankton for regulating dissolved oceanic nutrient ratios and highlights marine oxygen levels as a critical regulator in the Earth system. Understanding these connections could help scientists make more accurate predictions about the future of ecosystems and climate.
