Saildrone Completes First Autonomous Circumnavigation Of Antarctica

A seven-meter (23-foot) long, wind-powered unmanned surface vehicle (USV) called a Saildrone  has become the first unmanned system to circumnavigate Antarctica. The vehicle, known as SD 1020, was equipped with a suite of climate-grade sensors, and collected data in previously unchartered waters, enabling new key insights into ocean and climate processes. The 196-day mission was launched from Southport in Bluff,…

What is a Sponge

Sponges — simple aquatic animals with dense, yet porous, skeletons — are highly adapted to their environments. Sponges are found in a wide variety of colors, shapes, and sizes, and are often mistaken for plants. Scientists believe that their varied colorations may protect them from the sun’s harmful ultraviolet rays. Sponges have been around for a very long time, with…

What is Ocean Noise?

Ocean noise refers to sounds made by human activities that can interfere or obscure the ability of marine animals to hear natural sounds in the ocean. Many marine organisms rely on their ability to hear for their survival. Sound is the most efficient means of communication underwater and is the primary way that many marine species gather and understand information…
