Understand physical processes governing ice-ocean interactions in ice-shelf cavities

National Aeronautics and Space Administration (NASA) | Pasadena, California | United States | 5 days ago

. Description: Nearly half of Antarctica's ice mass loss comes from melting at the base of the ice shelf, known as basal melting (Rignot et al, 2013). As the ocean warms, we expect this contribution to increase

Coupled Water-Cycle Retrieval: Linking Precipitation and Soil Moisture Across NASA Microwave Missions

National Aeronautics and Space Administration (NASA) | Pasadena, California | United States | 5 days ago

-water-balance processes turns satellite soil moisture into an independent constraint on precipitation — a "natural rain gauge" complementary to atmospheric retrievals such as GPM, particularly over

Sources and Transformations of Organic Matter Across the Coastal Arctic River-to-Sea Continuum

National Aeronautics and Space Administration (NASA) | Greenbelt, Maryland | United States | 5 days ago

. Description: This research opportunity aims to characterize the seasonal variability of particle source materials and evaluate their nutritional content across the river-to-sea continuum of Alaska’s North Slope

The Atmospheric Infrared Sounder (AIRS): Greenhouse gas radiative forcing and water vapor feedback

National Aeronautics and Space Administration (NASA) | Pasadena, California | United States | 5 days ago

: the Arctic is releasing greenhouse gases because of permafrost melt. The response to radiative forcing is magnified by the  water vapor feedback. The scholar will spectrally decompose the observed water vapor

Stratosphere and Upper Troposphere Water Vapor Observations by SAGE

National Aeronautics and Space Administration (NASA) | Hampton, Virginia | United States | 5 days ago

. Description: Stratospheric water vapor (SWV) is a key element in the energy budget (climate), with a strong positive radiative forcing.  It also influences stratospheric aerosol microphysics and is implicated

Effect of Wildfires on the Ocean Biogeochemistry

National Aeronautics and Space Administration (NASA) | Greenbelt, Maryland | United States | 5 days ago

emissions from wildfires can lead to the atmospheric transport of macronutrients and bio-essential trace metals such as nitrogen and iron, which are later deposited over the ocean, potentially fertilizing

Submillimeter spectroscopy of sublimated interstellar and planetary ices

National Aeronautics and Space Administration (NASA) | Greenbelt, Maryland | United States | 5 days ago

technique that utilizes gas-phase, direct-absorption millimeter and submillimeter spectroscopy to detect and identify desorbed species from interstellar and cometary ice analogs. Many of the known

Laboratory Studies of Interstellar, Planetary, and Lunar Ices

National Aeronautics and Space Administration (NASA) | Pasadena, California | United States | 5 days ago

permanently shadowed regions (PSRs) of the Moon, and act as key drivers of chemical complexity on Ocean Worlds and small bodies. To interpret remote-sensing observations from current telescopes and spacecraft

Imaging Spectroscopy for Tropical Ecosystem & Biogeochemical Research

National Aeronautics and Space Administration (NASA) | Pasadena, California | United States | 5 days ago

, water, and nutrient cycles. Tropical forests in particular account for 40% of Earth's terrestrial biomass, yet they exhibit enormous structural, functional, and biogeochemical heterogeneity across

Instrument development for stratospheric composition

National Aeronautics and Space Administration (NASA) | Pasadena, California | United States | 5 days ago

microwave limb sounding systems, while also using the resulting measurements to investigate variability in upper troposphere–lower stratosphere (UTLS) ozone, water vapor, and carbon monoxide, advancing our
