Cyclone Biparjoy: India, Pakistan evacuate more than 170,000 – BBC News

The long-lived cyclone, Biparjoy is expected to make landfall near the border of India and Pakistan (courtesy of NASA Earth Observatory image by Lauren Dauphin, using VIIRS data from NASA EOSDIS LANCE, GIBS/Worldview, and the Joint Polar Satellite System (JPSS).

Gale force winds and heavy rains are lashing coastal parts of north-west India and southern Pakistan as a powerful cyclone makes landfall.

Forecasters say it could be the area’s worst storm in 25 years and warned it threatens homes and crops in its path.

The cyclone is due to barrel through parts of India’s Gujarat state and Sindh province in Pakistan….

“Death Star” Diatom – Steve Mandel

"Death Star" Diatom © 2021 Steve Mandel. These diatoms are from the ocean around Antarctica. The largest is Coscinodiscus bouvet. The stick-like spines that radiate out from the center of the diatom are Corethon pennatum. This slide was collected as part of an effort by two Ph.D. students, Allison Cusick and Martina Mascioni, who run the FjordPhyto program at Scripps Institute.

An enthusiastic and prolific nature photographer for over 25 years, Steve Mandel’s diverse portfolio includes astronomical imaging, wildlife photography, and the photography of microscopic marine organisms.

Steve is much more than a photographer with a camera. When he can’t find a camera that can capture the sort of imagery he believes is required to broaden our understanding of science and widen our perception, he will just BUILD it himself.

His photographs have appeared in the New York Times, Smithsonian Books, Reader’s Digest, Forbes Magazine, Sky&Telescope, Astronomy, and used by websites including NASA. Three of Steve’s images: of Japanese Macaques, Lemurs in Madagascar, and Proboscis Monkey have been given Highly Honored Awards by the Smithsonian Museum of Natural History and put on display at the Museum. He is also the recipient of the Astronomical Society of the Pacific’s International Amateur Achievement Award, and the American Astronomical Society’s Chambliss Amateur Achievement Medal.

California Against the Sea: Visions for our Vanishing Coastline – by Rosanna Xia

Book Cover, California Against the Sea: Visions for our Vanishing Coastline, by Rosanna Xia 2023 via Heyday Press.

Along California’s 1,200-mile coastline, the overheated Pacific Ocean is rising and pressing in, imperiling both wildlife and the maritime towns and cities that 27 million people call home. In California Against the Sea, Los Angeles Times coastal reporter Rosanna Xia asks: As climate chaos threatens the places we love so fiercely, will we finally grasp our collective capacity for change?

The (California) Coastal Act is a remarkable commitment to the public trust doctrine, which traces back to Justinian I, who declared in 533 C.E. that “the following things are natural law common to all: the air, running water, the sea, and consequently the seashore.” This notion — that certain lands should be held in trust by the government for the benefit of all people — evolved into English common law, which the United States then adopted and California later wrote into its state constitution…

As sand miners prosper in Uganda, a vital lake basin suffers – AP News

Sand Mining (by Sumaira Abdulali, CC BY-SA 3.0 via Wikimedia).

The excavator grunts in the heart of the wetland, baring its teeth. There are trucks waiting to be loaded with sand, and more almost certainly on the way.
This is how it is here daily in Lwera — a central Ugandan region on the fringes of Lake Victoria: a near-constant demand for sand that’s exerting pressure on a wetland that’s home to locals and animals and feeds into Africa’s largest freshwater lake…

A lifetime of research links Gulf of Mexico ‘dead zone’ to Midwest fertilizer runoff – Columbia Missourian

In the summer of 1985, Nancy Rabalais set sail on a research vessel into the Gulf of Mexico — and into the scientific unknown.Back then, scientists knew little about wide expanses of low-oxygen water, called hypoxia…That summer, Rabalais’ team was set on discovering how these areas connected to creatures that dwell on the bottom of the Gulf. While analyzing water and sediment samples miles off the coast, the team from the Louisiana Universities Marine Consortium and Louisiana State University quickly discovered that hypoxia stretched from the Mississippi River to Texas — and that it lasted for most of the summer…

Carlsbad considers joining other coastal cities in yet another sand replenishment project – the San Diego Union-Tribune

SANDAG asked Carlsbad to shoulder a proportional share of the $200,000 cost for a planning, feasibility and economic analysis needed to start the project, which would pull sand from the ocean and spread it on beaches from Oceanside to Imperial Beach….

UPDATE: The City Council unanimously opposed actively participating in the City of Oceanside’s sand nourishment pilot project during its April 11 meeting, remaining opposed to any plans that may obstruct the natural flow of sand down the San Diego County coastline.

However, the Carlsbad City Council agreed to request a city staffer be present during the neighboring city’s proposed pilot project meetings and design competitions…

Up to 70% of California beaches could disappear by end of the century – the Guardian

"What! Another Photo of Morro Rock?"(by loren chipman CC BY-NC 2.0 via Flickr).

A new study uses satellites to predict what California’s famous coastline could look like by 2100.

California is known for golden sands and endless waves, but much of the state’s famous shoreline could vanish in the future. That’s according to a new study, which found that between 25% and 70% of California beaches might be washed away by the end of the century, leaving only cliffs or coastal infrastructure in their wake…
