Since Charles Darwin’s day, the abundance of life on coral reefs has been puzzling, given that most oceanic surface waters in the tropics are low in nutrients and unproductive.
The scientists believe that this offshore energy may be entering the food web through lower-level plankton feeding fish that the groupers are then feeding on. This is likely to be supported by inputs of nutrient-rich deep water, which are little understood.
Soule talks to Physics World’s James Dacey about doing science in the Alvin submersible vehicle, which is currently be refurbished to allow it to reach the astonishing depth of 6.5 km.
Marine mammal researchers will share in $806,000 of federal funding for projects aimed at better understanding the threats of human-caused threats on endangered whale species.
In my personal opinion, the greatest coming-of-age story on Earth does not take place in a Dickens novel or a Disney movie, but rather in a white fish at the bottom of the Pacific Ocean.
This funding supports five research projects under two Oceans Protection Plan programs dedicated to reducing the threats marine mammals face in our increasingly busy and noisy coastal waters.
Using ropes, researchers explore chambers hundreds of feet below the surface of the Greenland ice sheet.
Hydrocarbons and petroleum are almost synonymous in environmental science. After all, oil reserves account for nearly all the hydrocarbons we encounter. But the few hydrocarbons that trace their origin to biological sources may play a larger ecological role than scientists originally suspected.
The whales are North Atlantic right whales, which number only about 360 in the world.
The culprit behind Florida’s red tides is the alga Karenia brevis. Near-annual blooms release toxins that harm marine animals and linger in the air, causing people on the coast to wheeze and cough. Little is known about what influences a red tide’s timing and severity, and tracking its impacts is expensive, time-consuming, and risky.
Douglas C. Webb, the founder of Teledyne Webb Research, North Falmouth, has received an honorary appointment to the position of Oceanographer Emeritus at Woods Hole Oceanographic Institution for his role in advancing knowledge of the Earth’s oceans.
Autonomous robotic fleets enable researchers to observe complex systems in ways that are otherwise impossible with purely ship-based or remote sensing techniques. In a time when the COVID-19 pandemic is reducing opportunities for researchers to go to sea, autonomous fleets offer an effective way to maintain a persistent presence in features of interest.
The research team was particularly interested in the deep chlorophyll maximum (DCM) layer. Also known as the subsurface chlorophyll maximum, the DCM exists below the surface of the ocean and holds the maximum concentration of chlorophyll, thus playing an important ecological role in the open ocean.
The robo-vessel will map the ocean floor, and its solar-powered sensors will sample fish DNA and collect climate data.
