  6. Mapping the Mozambique Channel

    The Mozambique Channel boasts some of the world’s most turbulent waters, driven by eddies hundreds of kilometers wide. Eddies of this size — known as mesoscale — determine regional flows that influence local biodiversity, sediment mixing, and how plastic pollution moves. To better understand the region, scientists measured a mesoscale dipole from a research vessel.

    Illustration of flows in the Mozambique Channel. The anticyclonic ring in dark blue rotates counterclockwise and consists of largely uniform water (labeled Ring: R1). To the south, in green, a cyclonic eddy rotates in a clockwise sense (labeled Cyclone: C1). This area is chlorophyll-rich and has varying salinity levels. Between the two is a filament of chlorophyll-rich water being drawn from the near-shore region (labeled Filament: F1).

    The dipole consisted of a large anticyclonic ring (shown in dark blue) that rotated counterclockwise and a smaller cyclonic eddy (shown in green) that rotated clockwise. Between these eddies lay a central jet moving up to 130 centimeters per second that drew material out from the shoreline. In the anticyclonic ring, researchers found largely uniform waters with little chlorophyll. The cyclonic eddy, in contrast, was high in chlorophyll and had large variations in salinity. Those smaller-scale variations, they found, helped to drive vertical motions of up to 40 meters per day.

    In situ measurements like these help scientists understand how energy flows through different scales in the ocean and how that energy helps transport nutrients, sediment, and pollution regionally. Such measurements also help us to refine ocean models that enable us to predict this transport and how regions will change as climate patterns shift. (Image credit: ship – A.

  11. Very cool to see a lot of people on Mastodon! Here is a little communication on a work:

    New performance "An Eye from Above" premiere in tsonami Festival - Valparaiso - 18 jan 25.

    For over 20 years, the three NOAA satellites have been crossing our sky at over 20,000 km/h, continuously scanning the Earth's clouds and radiant energies.

    An Eye from above is a performance that attempts to receive a live signal from one of these satellites, using an adapted antenna and a radio tuned to 137 MHz. As the satellite rises above our horizon, its signal slowly emerges from the surrounding noise, giving rise to a characteristic pulsation. The antenna acts as a revealer, making perceptible the electrical energy that passes through our bodies and our environment amidst a crowd of other artificial signals.

    Poetry of analog protocols: this pulsation can be decoded into an image. Slowly, line by line, a nephanalysis of the 2000 km that surround us appears. Clouds and infrared radiation from the ground are displayed, offering a shift from our point of view to that of a space object.
