Variability and trends in surface seawater pCO2 and CO2 flux in the Pacific Ocean

Variability and trends in surface seawater pCO2 and CO2 flux in the Pacific Ocean Kurishio Extension Observatory mooring. (Credit: NOAA) High-resolution moored time series of sea-air CO2 flux reveal seasonal to decadal variability influences detection of anthropogenic trends, according to CPO-supported paper published in Geophysical Research Letther. This study on partial pressure of carbon dioxide (pCO2) …

Biogeochemical Floats can be Used to Improve Measurements of Sea-Air CO2 Exchanges, Study Shows

Biogeochemical Floats can be Used to Improve Measurements of Sea-Air CO2 Exchanges, Study Shows A study published as an early online release on Global Biogeochemical Cycles shows the value of calibrated biogeochemical floats for providing data measurements of surface ocean partial pressure of CO2 ( pCO2sw ), which is measured to determine air-sea CO2 exchanges.  A certain degree of uncertainty …

Absolute Velocity Estimates from Autonomous Underwater Gliders Equipped with Doppler Current Profilers

Absolute Velocity Estimates from Autonomous Underwater Gliders Equipped with Doppler Current Profilers A study published in the Journal of Atmospheric and Oceanic Technology demonstrates the value of glider-based Acoustic Doppler Current Profilers (ADCP). ADCPs can take measurements with high-resolutions in the deep ocean, making them an efficient tool for sampling large areas in relatively short times. These …

Mixed-layer carbon cycling at the Kuroshio Extension Observatory

Mixed-layer carbon cycling at the Kuroshio Extension Observatory A study published in Global Biogeochemical Cycles contributes evidence that the Kuroshio Extension transition zone is a biological hot spot for carbon cycling within the North Pacific carbon sink region.  Researchers used data recorded over seven years at the NOAA Kuroshio Extension Observatory surface mooring in the North Pacific Ocean. NOAA …
