  • Gathering Ocean Intel From Above, On And Under The Waves

    Scientists and researchers across a range of organizations are engaged in a NASA-led campaign 110 nautical miles off of San Francisco to study small-scale ocean processes and dynamics, a study that is aiming to deliver better understanding of how these small processes impact the atmosphere above and below the waves. Perhaps more importantly, the S-MODE project aims to gather and correlate information from below, on and above the waves, a study that could eventually lead to tracking these small-scale processes via satellite to help better predict the weather and future climate.

  • NASA Invites Media to Learn About S-MODE Mission

    NASA held a media teleconference on Friday, Oct. 29 to share information about the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE), a campaign to study small ocean whirlpools, eddies, and currents. Understanding small-scale ocean dynamics will help scientists better understand how Earth’s oceans help slow climate change.

  • Unexpected Turbulence for the S-MODE Airborne Instruments

    DopplerScatt requires precise knowledge of its position and orientation so that its radar data that it collects can be processed on board and on the ground. These data are what we call navigation data and they come from a Global Positioning System/Inertial Motion Unit (basically a GPS) instrument aboard the DopplerScatt instrument. After the power on, DopplerScatt was unable to process data onboard. Post landing data were transferred to a ground server where they will be evaluated for usability. 

  • NASA aircraft to help study oceans

    An aircraft from NASA Armstrong Flight Research Center is taking part in a study of small ocean eddies, swirling areas of water that scientists believe impact how the ocean affects climate change.

    The Sub-Mesoscale Ocean Dynamics Experiment, or S-MODE, uses a combination of instruments taking measurements from the air, the ocean surface and underwater to study these spiraling eddies that were first observed from space during the Apollo 7 mission.

  • NASA launches ocean research mission off San Francisco

    The organisation better known for its space programmes seeks to find out in what way oceans are involved in climate change 100 miles off the San Francisco coast. As part of the mission, NASA has one ship, two airplanes, numerous robotic research vehicles and saildrones involved.

  • NASA launches mission off San Francisco coast to study ocean's relationship to climate change

    To study the role Earth’s oceans play in climate change, NASA recently launched a mission 100 miles off the San Francisco coast that involves a ship, two airplanes, and a fleet of saildrones and other robotic research vehicles.

  • Liftoff! Aircraft Experiments Take Flight for NASA’s S-MODE Mission

    The first of three aircraft participating in the S-MODE campaign has arrived at Moffett Field in California. The NASA King Air B200 aircraft, carrying two science instruments – DopplerScatt and MOSES – landed on October 18th and is preparing for its first flight early in the morning on October 19th. The weather conditions have been changing and incoming storms in northern California are throwing a wrench into our planning for the airborne part of the campaign. 

  • Instruments in the Sea and Sky: NASA’s S-MODE Mission Kicks off 1st Deployment

    Using instruments at sea and in the sky, the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) team aims to understand the role these ocean processes play in vertical transport, the movement of heat, nutrients, oxygen, and carbon from the ocean surface to the deeper ocean layers below. In addition, scientists think these small-scale ocean features play an important role in the exchange of heat and gases between air and sea. Understanding small-scale ocean dynamics will help scientists better understand how Earth’s oceans slow the impact of global warming and impact the Earth climate system.

  • NASA’s S-MODE Takes to the Air and Sea to Study Ocean Eddies

    After being delayed over a year due to the pandemic, a NASA field campaign to study the role of small-scale whirlpools and ocean currents in climate change is taking flight and taking to the seas in May 2021.

    Using scientific instruments aboard a self-propelled ocean glider and several airplanes, this first deployment of the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) mission will deploy its suite of water- and air-borne instruments to ensure that they work together to show what’s happening just below the ocean’s surface. The full-fledged field campaign will begin in October 2021, with the aircraft based out of NASA’s Ames Research Center in Mountain View, California.

    “This campaign in May is largely to compare different ways of measuring ocean surface currents so that we can have confidence in those measurements when we get to the pilot in October,” said Tom Farrar, associate scientist at the Woods Hole Oceanographic Institution in Massachusetts and principal investigator for S-MODE.

    The S-MODE team hopes to learn more about small-scale movements of ocean water such as eddies. These whirlpools span about 6.2 miles or ten kilometers, slowly moving ocean water in a swirling pattern. Scientists think that these eddies play an important role in moving heat from the surface to the ocean layers below, and vice versa. In addition, the eddies may play a role in the exchange of heat, gases and nutrients between the ocean and Earth’s atmosphere. Understanding these small-scale eddies will help scientists better understand how Earth’s oceans slow down global climate change.

  • S-MODE Conducts Field Campaign in Southern California

    After a 13-month delay to the start of science operations due to COVID-19, the Submesoscale Ocean Dynamics and Vertical Transport Experiment (S-MODE) investigation has officially started collecting data with a short field campaign that began on May 3. This campaign features flights based at the NASA Armstrong Flight Research Center (AFRC) main campus in Edwards, CA on the AFRC B200, a deployment of instrumented ocean Wave Gliders from the Woods Hole Oceanographic Institution (WHOI) and the Scripps Institution of Oceanography (SIO) that look at currents at depth and other environmental conditions, and a Twin Otter International (TOI) aircraft. The B200 is equipped with the JPL Doppler Scatterometry instrument (DopplerScatt) that measures ocean surface velocity and wind, and UCLA’s Multiscale Observing System of the Ocean Surface (MOSES) that measures sea surface temperature (SST). The TOI Twin Otter carries the SIO Modular Aerial Sensing System (MASS), which measures sea surface topography, SST, ocean color, and ocean surface waves.
     
    The week of May 3 marked a number of long-awaited firsts for S-MODE. On Monday, the first flight on the B200 with the combined payload of the JPL DopplerScatt and UCLA MOSES instruments flew lines between Catalina and San Clemente islands — an area of strong ocean currents. The research activities on Friday, centered at  Office of Naval Research experiment site about 350 km offshore of Los Angeles, allowed the science team to conduct joint operations for the first time among the four instruments listed above. This combination of instruments represents some of the key measurements that will be made during future S-MODE campaigns. Demonstrating successful joint operations among these platforms is a key milestone for the S-MODE investigation, and the science team is very pleased with the resulting data so far.
     
    The current experiment will continue until May 18 in preparation for the S-MODE October Pilot campaign, whose flight operations will be based at NASA Ames Research Center.

    S-MODE is supported by the Earth System Science Pathfinder (ESSP) Program Office at NASA Langley Research Center through the Earth Venture Suborbital-3 program and managed by the Earth Science Project Office (ESPO) at NASA Ames Research Center.

This is NASA’s third series of Earth Venture suborbital investigations, which are regularly solicited, sustained observation projects first recommended by the National Research Council in 2007. The first set of five projects was selected in 2010, and the second in 2014.

  • New Technology Doubles Scientists’ View of Ocean-Air Interactions

    NASA scientists are hard at work trying to unlock mysteries of our planet’s ocean surface currents and winds using a new Earth science radar instrument called DopplerScatt.

    Ocean currents and winds form a never-ending feedback loop: winds blow over the ocean's surface, creating currents. At the same time, the hot or cold water in these currents influences the wind's speed. Understanding the relationship between the two phenomena is crucial to understanding Earth's changing climate. Gathering data on this interaction can also help people track oil spills, plan shipping routes and understand ocean productivity in relation to fisheries.
