Water column data acquired by multibeam echosounders (MBES) imposes large requirements on disk storage and data transfer, so is typically logged only during specific times, a practice that poses the risk of missing interesting targets. Furthermore, huge data volumes from both bathymetry and water column data can lead to huge burdens for the operators during long surveys. MBES data is often compressed using standard solutions such as Zip or 7-Zip, but these can be computationally heavy for a relatively modest size reduction. To overcome this, we developed FAPEC, a high-performance data compression software, now supporting MBES data. We also present FARSHY, a fast visualization and analysis tool to

A ship set sail from Connecticut in May to spend three months offshore hunting for freshwater deep beneath the Atlantic Ocean.

This summer scientists drilled deep below the Atlantic Ocean off the coast of northeastern US and tapped into a huge, mysterious reservoir of freshwater — what they discovered could have big implications for a world grappling with an increasingly severe water crisis.
The existence of freshwater beneath the Atlantic has been known for decades, but it had remained virtually unexplored. In the 1960s and 70s, scientific expeditions and companies drilling the ocean for resources such as oil would sometimes hit fresh water.
Then, in 2019, scientists from Woods Hole Oceanographic Institution and Columbia University announced a “surprising discovery.”

US oil production rose to record highs in September, data from the Energy Information Administration (EIA) showed on Friday, shrugging off concerns that the market is heading towards a surplus.
US crude oil output rose 44,000 barrels per day in September to a record 13.84 million bpd, according to EIA data.
Oil output from New Mexico, the second-largest oil producing state, hit a record 2.351 million bpd, while output from the federal offshore gulf region rose to 1.983 million bpd in September, the highest since February 2020.
Future US oil production growth is expected to be concentrated in the offshore gulf region as the

Cross section of the core of a mature hurricane.
The axisymmetric primary swirling motion (curved black arrows) of the vortex is sustained by a radial and vertical secondary circulation (red arrows) that consists of frictional inflow that loses angular momentum to the sea as it gains moist enthalpy and a convective updraft around the eye that turns the latent heat into sensible heat to provide the buoyancy needed to loft air from the surface to tropopause level.
The updraft entrains midlevel air promoting mass and angular momentum convergence (blue arrow). It is this inflow that supplies the excess angular momentum needed to spin up the vortex. Precipitation driven convective updrafts (vertical black arrow) form as hydrometeors fall from the outward

En meteorología, una depresión se refiere a una zona de baja presión en la atmósfera, caracterizada por el ascenso del aire, la formación de nubes y, a menudo, asociada a condiciones meteorológicas inestables como lluvia, vientos fuertes y tormentas. Las depresiones, también llamadas ciclones en términos meteorológicos, se forman cuando el aire cálido y húmedo asciende, provocando una caída de la presión atmosférica. Estos sistemas son comunes en latitudes medias y suelen atravesar océanos y continentes, influyendo en los patrones meteorológicos y afectando las condiciones de navegación.
Comprender las depresiones es esencial para los navegantes, ya que los sistemas de baja presión pueden provocar cambios meteorológicos rápidos y severos, que afectan la visibilidad, la dirección del viento y el estado del mar. El estudio
