There is no time to lose

Carbon dioxide levels continue at record levels, despite COVID-19 lockdown, the WMO reports. The increase in carbon dioxide from 2018 to 2019 was larger than that observed from 2017 to 2018 and larger than the average annual growth rate over…

Scientists call for decade of concerted effort to enhance understanding of the deep seas

(University of Plymouth) An international team of scientists, spanning 45 institutions in 17 countries, has called for a dedicated decade-long programme of research to greatly advance discovery in the deep ocean.

True origin of oldest evidence of animals

Scientists have resolved a longstanding controversy surrounding the origins of complex life on Earth. The studies found molecular fossils extracted from 635-million-year-old rocks aren’t the earliest evidence of animals, but instead common algae.

Large predatory fish thrive on WWII shipwrecks off North Carolina coast

Results of an expedition to a sunken U-boat and Nicaraguan freighter offer a detailed glimpse into unexpected ‘islands of habitat.’

Love waves from the ocean floor

Supercomputer simulations of planetary-scale interactions show how ocean storms and the structure of Earth’s upper layers together generate much of the world’s seismic waves. Decoding the faint but ubiquitous vibrations known as Love waves could yield insights about Earth’s storm history, changing climate and interior.

Above Zero Celsius at North Pole November 2020

Above image shows that, in October 2020, the Arctic Ocean was very hot. The Copernicus image below shows temperatures averaged over the twelve-month period from November 2019 to October 2020. Keep in mind that, in the Copernicus image, anomalies are…

Ancient life signs under dinosaur-killing Chicxulub crater

Researchers have found evidence for an ancient microbial ecosystem in a hydrothermal system beneath Mexico’s Chicxulub Crater, thought to be the site of the impact that killed the dinosaurs 66 million years ago.

New Study Eliminates Confidence In Human Attribution For Modern Global Warming

The forcing uncertainties and lack of observational measurements in the top-to-bottom global ocean preclude an assessment that modern warmth is due to anthropogenic activities. Key points from a new paper (Gebbie, 2021): • 93% of the changes to the Earth’s…

Decaying jellyfish blooms can cause temporary changes to water column food webs

(Frontiers) Decaying jellyfish blooms fuel the rapid growth of just a few specific strains of seawater bacteria, causing temporary changes to the water column food web. This is the finding of a new study furthering our understanding of how jellyfish blooms, which are happening with increasing frequency, impact marine ecosystems. It details these fast-growing bacteria effectively reduce the amount of jellyfish detrital material reaching the seafloor, keeping it instead within the water column food web.

World’s Largest Seagrass Restoration Project is a Virginia Success, Planting 600 Acres That Grow to Become 9,000

In what started as an experiment and became the largest success of its kind, a seagrass restoration project in Southeast Virginia is demonstrating the resilience of marine ecosystems when they are given a chance to recover. A group of marine scientists and volunteers spread more than 70 million eelgrass seeds across a 200-hectare plot off […]
