Australia’s icebreaker RSV Nuyina which was promoted as representing a “quantum leap forward for scientific research capabilities,” continues to be at the center of a controversy with the latest report highlighting that it has failed to conduct any scientific voyage since its launch in 2021.
RSV Nuyina, which is operated by Australian Antarctic Division (AAD) cost A$534.4 million (US$350 million) to build, but the icebreaker has had a troubled history. Since the vessel was completed in 2021, it has experienced mechanical failures that have raised concerns. A new report from the Australian federal government criticizes the vessel’s failure to carry out

Los sistemas autónomos marítimos (MAS, por sus siglas en inglés) de superficie y submarinos, sobre todo los planeadores submarinos, son desde hace algunos años esenciales para apoyar las observaciones ambientales y las actividades de la economía azul. Estos vehículos ágiles y rentables pueden transportar cargas útiles científicas a más de 6 000 m de profundidad. Pero para aprovechar todas las ventajas de estos activos, es necesario contar con una infraestructura capaz de satisfacer distintas demandas, desde la investigación y vigilancia marinas hasta los servicios públicos y las necesidades de la industria.

When the ocean's average surface temperature hit a new record high in March 2023, it set off alarm bells in the scientific community - but few experts predicted that ocean temperatures would keep climbing off the chart. The average sea surface temperature has set a new daily record every day for the past 12 months, and is now beating the records set last March.
In the near term, the most immediately visible effect has been coral bleaching - the loss of photosynthetic algae that lives on (and grows)

Types and Causes of Tidal Cycles –
Diurnal, Semidiurnal, Mixed Semidiurnal; Continental Interference
If the Earth were a perfect sphere without large continents, all areas on the planet would experience two equally proportioned high and low tides every lunar day. The large continents on the planet, however, block the westward passage of the tidal bulges as the Earth rotates. Unable to move freely around the globe, these tides establish complex patterns within each ocean basin that often differ greatly from tidal patterns of adjacent ocean basins or other regions of the same ocean basin (Sumich, J.L., 1996).
Three basic tidal patterns occur along the Earth’s major shorelines. In general, most areas have two high tides and two low tides each day. When
