About Stanford Earth Matters

Farming seaweed

Blue food revolution

Hunger, malnutrition and obesity affect billions of people. A first-of-its-kind comprehensive review of the so-called blue foods sector reveals challenges and opportunities for creating a healthier, more sustainable, equitable and resilient global food system.

Fish market in Vietnam

Study suggests rising and shifting demand for seafood by 2050

Humanity is likely to consume more fish and shellfish in the coming decades. Preparing for that future requires better data on the types of fish that people eat, sustainable expansion of aquaculture and improved understanding of the local context for the food on our plates.

Peel River

Longest known continuous record of the Paleozoic discovered in Yukon wilderness

Stanford-led expeditions to a remote area of Yukon, Canada, have uncovered a 120-million-year-long geological record of a time when land plants and complex animals first evolved and ocean oxygen levels began to approach those in the modern world.

Fungus creates a fast track for carbon

New research focused on interactions among microbes in water suggests fungal microparasites play a bigger than expected role in aquatic food webs and the global carbon cycle.

Biodiversity loss in warming oceans

A fossil study from Stanford University finds the diversity of life in the world’s oceans declined time and again over the past 145 million years during periods of extreme warming. Temperatures that make it hard for cold-blooded sea creatures to breathe have likely been among the biggest drivers for shifts in the distribution of marine biodiversity.

Loggerhead sea turtle underwater

Illuminating a sea turtle mystery

North Pacific loggerhead turtles’ years-long oceanic journeys remain poorly understood. Using data from satellite tracking and other techniques, scientists reveal a unique phenomenon that may explain the endangered migrants’ pathway.

Mackerel school

Aquaculture’s promise and peril

Twenty years ago, a Stanford-led analysis sparked controversy by highlighting fish farming’s damage to ocean fisheries. Now a follow-up study takes stock of the industry’s progress and points to opportunities for sustainable growth.

Melting iceberg

Research and policy in a changing Arctic

Stanford University scholars discuss the Biden administration’s early actions on environmental issues in the Arctic and how the U.S. government can address threats to ecosystems, people and infrastructure in the fastest-warming place on Earth.

Small-scale fisheries offer strategies for resilience in the face of climate change

Small-scale fisheries, which employ about 90 percent of the world’s fishers and supply half the fish for human consumption, are on the frontlines of climate change. They may offer insights into resilience.

Fish swimming in plastic debris

Plastic ingestion by fish is a growing problem

A new research review finds the rate of plastic consumption in fish has doubled in the past decade and continues to increase. Fish higher up on the food chain are at the greatest risk.

Sulfur plays a role in the ocean carbon cycle, study finds

The results suggest a possible feedback that could help trap carbon in the ocean’s low-oxygen zones, but the impact on climate change remains unclear.

Editor's picks: Top 10 stories of 2020

Our list includes a mix of favorites, high-impact stories and some of our most-read research coverage from a tumultuous year.

Reef crevice

Combining light and sound to see underwater

The “Photoacoustic Airborne Sonar System” could be installed beneath drones to enable aerial underwater surveys and high-resolution mapping of the deep ocean.

Under ice bloom

Understanding the Arctic's hidden phytoplankton blooms

A growing body of evidence suggests tiny marine algae can bloom in the darkness below sea ice in the Arctic Ocean – and that such blooms occurred even before climate change began affecting the region's ice cover.

Could kelp help relieve ocean acidification?

A new analysis of California’s Monterey Bay evaluates kelp’s potential to reduce ocean acidification, the harmful fallout from climate change on marine ecosystems and the food they produce for human populations.

Ocean storm

Undersea origins of Earth's mysterious Love waves

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.

Blue whale

Pattern in whale songs predicts migration

Through the use of two advanced audio recording technologies, a collaboration of Monterey Bay researchers has found that blue whales switch from nighttime to daytime singing when they are starting to migrate.

Northern California coast

Newly identified 'landfalling droughts' originate over ocean

Researchers have identified a new type of “landfalling drought” that originates over the ocean before traveling onto land, and which can cause larger, drier conditions than other droughts.
