A new study warns that climate change “velocity” in the deep ocean — the rate at which species’ range shifts in order to remain at their preferred temperature — is greater than at the surface even if we mitigate climate change, and particularly at depths below 600 and 3000 feet. Surface warming is not expected to change nearly as much as the warming at deeper layers in the ocean, causing different velocities in different layers of the ocean.
Why This Matters: The differences in water temperature increases at different depths in the water column could cause major disruptions in food webs as species that rely on each other for survival will have to adapt at different velocities, thus having major impacts on the distribution and abundance of ocean wildlife. The overall impacts could be catastrophic because marine life in the deep ocean will be threatened increasingly through the end of the century due to warming regardless of our actions now. Which makes it all the more important that globally we protect special areas in the ocean from other threats like mining and overfishing. And we must anticipate species shifts before creating marine parks in the high seas so they actually can protect critical species and habitat.
by Amy Lupica, ODP Staff Writer A new study has found that half of the nation’s tidal marshes are at risk of being destroyed by sea-level rise, most of them along the southern coasts of the contiguous U.S. Now, members of the Gullah/Geechee Nation, whose one million residents live along coastal areas stretching from Jacksonville, North Carolina, to […]
by Amy Lupica, ODP Staff Writer St. Petersburg, Florida, has fallen victim to what could be one of the most prolonged red tides in recent history. Hundreds of tons of dead sea life have washed up on shores as the ecological disaster takes root, and experts say the end isn’t yet in sight. Officials are trying to pinpoint […]
Seaweed could be the next crop sensation, as seaweed farms on the coast of Bali, Indonesia, take root underwater. India-based Sea6 Energy has designed a “sea combine” in the hopes of boosting the now small seaweed market to the forefront of sustainable aquaculture. The innovative catamaran sweeps over fields of seaweed, harvesting and replanting it […]
