Needle in a haystack: identifying vulnerable marine ecosystems in the deep sea

Seamounts are underwater mountains rising thousands of feet from the bottom of the ocean. Due to their size and shape, seamounts exert a strong influence on local currents that results in nutrient enrichment and increased food supply. As a result, these massive features are often highly productive ‘oases’ in the deep sea, supporting a large … Continue reading Needle in a haystack: identifying vulnerable marine ecosystems in the deep sea

The Hunt for a Super Coral: Can Cold-Water Corals Adapt to Ocean Acidification?

When most people think of a coral reef they are imagining a sunny tropical beach, but many coral species are actually found in the dark, cold waters of the deep sea1. These corals, commonly known as cold-water corals due to their preference for low temperatures, form beautiful ecosystems that are teeming with life. One of … Continue reading The Hunt for a Super Coral: Can Cold-Water Corals Adapt to Ocean Acidification?

A Tale of Two Cold-Water Coral Reefs

Human industrial and agricultural activity has released massive quantities of carbon dioxide (CO2) into our atmosphere, with significant effects on our climate and oceans. About one-third of this atmospheric CO2 is absorbed by our oceans1, where it chemically interacts with seawater to reduce its pH – a scale that measures how acidic (lower pH values) … Continue reading A Tale of Two Cold-Water Coral Reefs

Seamounts: oases of biodiversity in California’s deep waters

Beneath the deep waters off the coast of California exist submarine mountains that rise thousands of feet off the seafloor and harbor an incredible diversity of marine life. These underwater mountains are known as seamounts, classically defined as seafloor features that are taller than 1,000 m (3,300 feet), have steep sides and are roughly circular … Continue reading Seamounts: oases of biodiversity in California’s deep waters
