Daily precipitation ITCZ states for observations, reanalyses, and 25 CMIP6 models for “We need to simulate more northern ITCZs and less southern ITCZs over the east Pacific Ocean in coupled climate models.” Nov 24, 2025 - Physical Oceanography Gonzalez, Alex, 2025, "Daily precipitation ITCZ states for observations, reanalyses, and 25 CMIP6 models for “We need to simulate more northern ITCZs and less southern ITCZs over the east Pacific Ocean in coupled climate models.”", https://doi.org/10.26027/DATAHCNII0, MBLWHOI Library Dataverse, V1, UNF:6:SBnn9o9RjBRK7IaJUFHnVw== [fileUNF] Tropical precipitation biases have persisted since the very first generations of climate models. These biases are highly sensitive to the region and/or season of interest, with commonalities in the east Pacific and Atlantic Ocean basins, possibly due to their similar observed climatological northern hemisphere intertropical convergence zone (ITCZ)....
Flow cytometric data from DAPI-stained Dinophysis acuminata (DAMV01) cells cultured in prey-saturated and prey-limited conditions over four days in March 2024 Aug 20, 2025 - Biology Sung-Clarke, Serena; Ayache, Nour; Zhang, Wenguang; Smith, Juliette; Tong, Mengmeng; Brosnahan, Michael, 2025, "Flow cytometric data from DAPI-stained Dinophysis acuminata (DAMV01) cells cultured in prey-saturated and prey-limited conditions over four days in March 2024", https://doi.org/10.26027/DATAFNVBB1, MBLWHOI Library Dataverse, V1, UNF:6:A3dKuAkyNYLCjtT2Ky8Kkg== [fileUNF] This dataset consists of a flow cytometry experiment from two cultures of Dinophysis acuminata. Cell samples were extracted from cultures that were saturated vs limited in its prey, Mesodinium rubrum, every two hours for 96 hours (4 days). Cellular DNA was stained with DAPI, which was then analyzed for particle scatter (forward, side) and fluoresce...
Physical Oceanography(Woods Hole Oceanographic Institution) Aug 12, 2025 The ocean plays a critical role in Earth’s climate and is necessary to sustain life on our planet, yet we still have much to learn about how it is changing due to natural and anthropogenic forces. As physical oceanographers, we make new observations of the oceans and use physics, mathematics, computer models and statistics to better understand how...
Biology(Woods Hole Oceanographic Institution) Aug 12, 2025 Oceanic biology is extraordinarily complex because of the diversity of organisms that inhabit the seas, the wide range of environments they inhabit, and the varied and complex ways in which they interact with and contribute to essential global processes. Research in the Biology Department at WHOI encompasses a diversity of organisms, levels of biol...
Spatial mapping of dissolved methane using an in situ sensor in Puget Sound Aug 11, 2025 - Applied Ocean Physics & Engineering Michel, Anna, 2025, "Spatial mapping of dissolved methane using an in situ sensor in Puget Sound", https://doi.org/10.26027/DATAZAL2SC, MBLWHOI Library Dataverse, V1 Release of methane, as gas bubbles or in the dissolved phase, from the seafloor has been observed in coastal waters (<200 m) and deep ocean basins (>1000 m). Methane dissolution within the water column affects the geochemistry of the surrounding water, leading to localized oxygen loss and ocean acidification. Traditional methods for detecting and q...
A Refractometer for Measuring Thermohaline Density Microstructure in the Ocean Jul 21, 2025 - Applied Ocean Physics & Engineering Jason Kapit; Farr, Norman; Schmitt, Raymond, 2025, "A Refractometer for Measuring Thermohaline Density Microstructure in the Ocean", https://doi.org/10.26027/DATAVI1X45, MBLWHOI Library Dataverse, V1, UNF:6:epQsmNnadTTL3W7CWhGEyA== [fileUNF] Here we report an optical sensor for measuring millimeter-scale thermohaline density variations in the ocean. The instrument is based on a fiber Fabry-Perot white light interferometer which can resolve the refractive index of water to better than 2 x 10-8 within a sample volume smaller than 1 mm3 at a sample rate of 500 Hz. This equates to detectab...
An Underwater Methane Sensor Based on Laser Spectroscopy in a Hollow Core Optical Fiber Jul 21, 2025 - Applied Ocean Physics & Engineering Jason Kapit; Youngs, Sarah; Pardis, William A.; Padilla, Alexandra M.; Michel, Anna, 2025, "An Underwater Methane Sensor Based on Laser Spectroscopy in a Hollow Core Optical Fiber", https://doi.org/10.26027/DATAPTD8ZF, MBLWHOI Library Dataverse, V1, UNF:6:S+yqkS17186lU0QS3EbOOA== [fileUNF] Existing sensors for measuring dissolved methane in situ suffer from excessively slow response times or large size and complexity.
