In a recent study, scientists explored the reasons behind the existence of the Indian Ocean Geoid Low, a point of low gravity found just south of the Indian peninsula.

A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study.

A new study from researchers at UCLA and the University of Houston reveals estimates of significant groundwater loss in California’s Central Valley during the recent drought and sparks questions of sustainability for the important agricultural area.

A team of scientists led by postdoctoral researcher Takatoshi Sakazaki, from the University of Hawaiʻi at Mānoa’s International Pacific Research Center (IPRC), has analyzed satellite-based observations and computer model simulations of tropical rainfall variation throughout the day in an effort to determine the root cause of the temporal patterns. Their results, accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union, show that daily tropical rainfall distribution is significantly shaped by heating of the upper atmosphere.

Urban plants offer city dwellers many benefits, such as improved health and decreased crime and pollution. And now we have even more reason to green our cities. A new study from the Water Sustainability and Climate project at the University of Wisconsin-Madison indicates that adding more greenery to the urban landscape could help urban vegetation cope better with the summer heat and a warming climate. In other words, the more plants in a city, the merrier they all are.

Researchers have discovered a large concentration of sediment deposits at the end of Monterey Canyon, an underwater chasm beneath Monterey Bay, California. The sediment deposits are relatively young and may be more likely to catalyze underwater landslides than other sections of the canyon, according to the researchers who presented their discovery at the 2016 American Geophysical Union Fall Meeting.

Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study. Groundwater is a vital source of water in the western United States and will be increasingly important with continued population growth and climate variability. Understanding the role of these large recharge events in replenishing aquifers and sustaining water supplies is crucial for long-term groundwater management.

Earth’s carbon cycle is heavily influenced by ecological processes in the ocean. The quantification and understanding of the intricate relationships between carbon dioxide and ocean ecosystems, EXPORTS and what effects these have on the present and future conditions on Earth, is one of the greatest challenges in oceanography. One of the most important aspects that preclude the full understanding of the ocean carbon cycle is the lack of parallel measurements at a global scale; this also hinders our ability to make robust predictions in an uncertain future. The EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) Science Plan was proposed to NASA in order address this knowledge gap. It aims at developing a predictive understanding of the export and fate of global ocean net primary production (NPP) and its implications to the ocean carbon cycle for present and future climates. The goal of this project is to quantify of the mechanisms that control the export of carbon from the euphotic zone as well as its fate in the underlying “twilight zone”.

Spring snowpack, relied on by ski resorts and water managers throughout the Western United States, may be more vulnerable to a warming climate in coming decades, according to a new study.
