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)

La ballena franca del Atlántico norte #3720 y su cría fueron avistadas por primera vez frente a la isla Wassaw, Georgia, el 19 de enero de 2021. NOAA Fisheries se asociará con la NASA y el sector privado para desarrollar etiquetas satelitales que mejoren la detección de ballenas y reduzcan el riesgo de colisiones con embarcaciones. (Crédito de la imagen: Clearwater Marine Aquarium Research Institute, tomada con el permiso NOAA n.º 20556-01)

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

SURFING

Welcome to Pororoca, one of the longest waves in the world. The tidal bore travels up to 500 miles (804 kilometers) upstream of the Amazon River in northern Brazil.

It's an impressive natural phenomenon that forever remains in the memory of those who see it and ride it.

The word Pororoca should come from the indigenous Tupi word "porórka," meaning "great roar," or from the aboriginal term to express the act of destroying everything.

Brazil is one of Nature's sanctuaries on Earth, home to rich fauna and flora and the epicenter of nearly all natural events.

French oceanographer and filmmaker Jacques Cousteau was the first person to document Pororoca aboard his RV Calypso research vessel on March 28, 1982.

The film "Journey
