The Great Barrier Reef of the Americas: Coastal Lessons from the Past

The Great Barrier Reef of the Americas: Coastal Lessons from the Past

This is part 1 of a two-part series concerning Richard Condrey and Natalie Peyronnin’s recent paper, “Using Louisiana’s coastal history to innovate its coastal future,” published in Shore & Beach, Fall 2017. See part 2 here.

They were there, billions of oysters on the Great Barrier Reef of the Americas (GRBA), along the southern coast of Louisiana – a dangerous impediment to navigation. Just three to four feet under

When you think about the English computer scientist Alan Turing you most probably think of either his code-breaking efforts at Bletchley Park during World War II or his early hypotheses about artificial intelligence, which resulted in the formulation of the famous Turing Test.

Something you probably don’t associate him with? Groundbreaking chemistry — and, more specifically, groundbreaking chemistry which could soon be used to provide people around the world with

Melting ice shelves are changing the ocean’s chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change models.

At the North and South Poles, cold dense … [more…]

Oxygen Crisis in World’s Oceans

Oxygen Crisis in World's Oceans

In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than 10-fold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms.

To halt the decline, the world needs to rein in both climate change and nutrient pollution, an international … [more…]

The lesser-known threat from sea-level rise? Saltwater intrusion into Florida’s freshwater wells.

When it comes to sea-level rise, Miami is usually deemed ground zero. Time-lapse maps depict the creeping rise of blue, ultimately inundating South Florida and other coastal regions.

You don’t have to go to climate-apocalypse movies like the Day After Tomorrow to see flooding of a major American city. It’s a reality as South Florida residents become familiar with wading down the street through high waters or kayaking around their
