Technique designed to predict how much energy waves will be bringing

This item was filled under Climate
Marine energy has a great future potential according to the experts, but there is still a long way to go before it can be used on a large scale. A team of researchers has now developed a technique to forecast wave energy several hours in advance....

Better daily sea ice forecasts for the Arctic

This item was filled under Climate
Ice experts have developed a straightforward new technique for estimating sea ice concentration in the Arctic Ocean, and the new method improves the US Navy's short-term sea ice forecast of ice edge location by almost 40 percent. With shipping on the rise in the Arctic Ocean, improving these short-term forecasts makes navigating in Arctic waters safer....

Intensity of desert storms may affect ocean phytoplankton

This item was filled under Climate
Scientists have determined that once iron is deposited in the ocean, it has a very short residence time, spending only six months in surface waters before sinking into the deep ocean. This high turnover of iron signals that large seasonal changes in desert dust may have dramatic effects on surface phytoplankton that depend on iron....

Improved NOAA Forecast for Red Tide in Florida

This item was filled under News


Red tide forecasts for Florida will now be even more accurate thanks to an improved method of forecasting that will allow NOAA scientists to see more clearly where the harmful algal blooms (HABs) that cause this phenomenon are located. This will help local residents and visitors make better decisions about their recreational choices during a HAB event and aid public health managers who coordinate response efforts and mitigate the effects of red tide.

What would a tsunami in the Mediterranean look like?

This item was filled under Climate
Researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece....

DNA sequencing used to identify thousands of fish eggs

This item was filled under Climate
Using DNA sequencing, researchers have accurately painted a clear picture of fish spawning activities in a marine protected area and have created a baseline for continuing studies on the effects of climate variability on fish populations. Researchers collected 260 samples off the Ellen Browning Scripps Memorial Pier over a two-year period and used DNA barcoding to accurately identify over 13,000 fish eggs....

Lab experiments question popular measure of ancient ocean temperatures

This item was filled under Climate
The membranes of sediment-entombed archaea are an increasingly popular way to determine ocean surface temperatures back to the age of the dinosaurs. But new results show that changing oxygen can affect the reading by as much as 21 degrees C....

Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study....

Foes can become friends on the coral reef: How seaweed becomes coral’s ‘friend’ when sea stars invade

This item was filled under Climate
On the coral reef, knowing who's your friend and who's your enemy can sometimes be a little complicated. Take seaweed, for instance. Normally it's the enemy of coral, secreting toxic chemicals, blocking the sunlight, and damaging coral with its rough surfaces. But when hordes of hungry crown-of-thorns sea stars invade the reef, everything changes, reports a new study....
