In the Berlin-Ichthyosaur State Park in the Humboldt-Toiyabe National Forest in Nevada, there is a fossil bed in which many ichthyosaurs (Shonisaurus popularis) have been found petrified in stone.

Over the years, there has been speculation that they had perished in a mass stranding incident or due to a nearby algal bloom. While these were possible, there had not been strong evidence to support these theories.

Marine scientists have invented a small device that can reduce shark bycatch numbers by emitting short electrical pulses as a deterrent.

When clipped on the fishing line next to a baited hook, the battery-operated SharkGuard works by emitting a short localised pulse every two seconds. This causes the shark’s ampullae of Lorenzini (electrical sensors around its nose and mouth) to be overstimulated, thus prompting it to swim away.

For the most part, most research have focussed on the impact of oceanic temperature changes on adult animals, but few looked at the animals' early life stages. A study by researchers from the University of California, Santa Barbara gives a useful insight into this specific area. 

Focussing on the larvae of the Kellet's whelk, a common sea snail in Southern California, it showed that rising temperatures will adversely impact the larvae. 

From March to July, phytoplankton blooms emerge along Calfornia’s Central Coast, as seasonal winds push the top layer of the waters out to sea, thereby allowing the cooler, nutrient-rich waters to rise to the surface.

Many marine animals are drawn to such oceanic upwellings, which consequently turn into their feeding grounds. For instance, krill gather to feed on the abundant phytoplankton, whilst blue whales converge to feed on the krill.

Once the upwelling ceases, these marine creatures move elsewhere.

This was my first visit to a Baltictech conference. At long last, I finally got the chance as it wasn't held almost at the same time as DEMA—which is always a priority because of the significant amount of our business we conduct there.

Baltictech, like other such conferences, has been held every other year in recent years, but not since 2019 due to the epidemic so this time around, there was a three-year break.

The SS Pacific was on its way from Puget Sound and Victoria to San Francisco when it collided with a big sailing ship in the dark off Cape Flattery on November 4, 1875 and sank in less than an hour. The Pacific had an estimated 275 passengers and crew aboard of which only two survived, making the sinking the most deadly maritime disaster in Northwest history. 

Only a handful of details of what happened came to light afterwards because there were only two survivors—one who floated around on debris for 40 hours, and another for 80 hours.

If you are thinking about going on a romantic getaway to Indonesia with your significant other, you should probably reconsider your choice of destination if you are not married. Indonesia's parliament has approved a new criminal code that bans sex outside marriage with a punishment of up to one year in jail.

On Friday 25 November, diver Arthur Castillo, 60, was found guilty of the involuntary homicide of his long-time dive buddy Christine Gauci who died following a dive in Mgarr ix-Xini, a bay on the southern coast of Gozo in January 2020. Ms Gauci was an Armed Forces of Malta member, diving instructor and technical diver.

The court handed Mr. Castillo a two-year jail term suspended for four years, pronouncing itself convinced that this case did not merit effective imprisonment. Castillo told Times of Malta he will be appealing the judgment but declined further comment.

After studying more than 23,000 sperm whale vocalisations recorded from 1978 to 2017 in the Pacific Ocean, researchers have concluded that sperm whales use distinctive vocalisations to identify themselves with specific whale clans.

Called “identity codas,” these vocalisations comprise sequences of clicking sounds that distinguish different social groups. They are different from non-identity vocalisations used across all the different whale clans.
