This year, we have the pleasure of welcoming Dr. Andrew Rypel to UC Davis and the Center for Watershed Sciences to his appointment as the new Peter B. Moyle and California Trout Endowed Chair in Coldwater Fishes. Dr. Rypel shares some of this thoughts about fish, science, and his new position:
In a drying time, Mars may have been kept warm enough for liquid water to remain stable on the surface thanks to explosive bursts of methane gas, a new study finds. The simulations, described in the journal Nature Geoscience, could explain how Mars managed to sustain a series of lakes in a climate that at first glance seems too cold and arid to have done so.
After five years of drought, the 2017 water year brought unexpectedly heavy precipitation, ranking second only to 1983 as California’s wettest year for statewide runoff. The dramatic swing in water conditions highlights the need to develop better long-range weather forecasting to cope with the state’s highly variable annual precipitation. … “Current short-term forecasting for seven days out is 70 percent accurate, while the 14-day forecast is only seven percent accurate,” said DWR Director Grant Davis.
The U.S. Geological Survey joins its many partners in other federal agencies, at universities, and in state and local governments in recognizing the importance of the Water Resources Research Act (WRRA) of 1964.
Signed into law 50 years ago by President Lyndon B. Johnson on July 17, 1964, the WRRA established a Water Resources Research Institute in each state and Puerto Rico.
A new global geologic map of Mars –the most thorough representation of the “Red Planet’s” surface – has been published by the U.S. Geological Survey. This map provides a framework for continued scientific investigation of Mars as the long-range target for human space exploration.
Seasonal carbon dioxide frost, not liquid water, is the main driver in forming gullies on Mars today, according to a recent U.S. Geological Survey study that relied on NASA’s Mars Reconnaissance Orbiter’s (MRO) repeated high-resolution observations.
[Jim] Walker and construction crews building a new 220-foot-high dam at Calaveras Reservoir in the remote canyons east of Milpitas have been digging up a prehistoric treasure trove: the teeth of an extinct hippopotamus-like creature called a Desmostylus, clams, barnacles and the giant teeth from a 40-foot-long shark — and what could turn out to be an entire whale skeleton.
“During the last year, whole oceans worth of water have been found in the [Earth's] mantle, hundreds of kilometers below the crust. And a paper in today’s [June 12] issue of Science traces water’s influence all the way down to an important boundary inside the Earth, the top of the lower mantle.”
“California’s drought is imperiling tricolored blackbirds, large trees and native fish, with some of the affected species already on the state’s endangered list and others likely headed there because of rapidly declining numbers, scientists say.”
“On her way to visit the Kearney Agricultural Research and Extension Center in Parlier on Monday, University of California President Janet Napolitano got a bird’s eye view of California cropland and rivers dry from the drought — a sight she hopes the universities can help fix through continued research and outreach.”
“By crunching data from the Central Valley, eBird can generate maps showing where virtually every species congregates in the remaining wetlands. … The BirdReturns program, financed by the Nature Conservancy, then pays rice farmers in the birds’ flight path to keep their fields flooded with irrigation water from the Sacramento River as migrating flocks arrive.
From the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC):
“Drought is a unique climate event, which often begins with subtle effects but can end up being incredibly costly and devastating. Paleoclimatology, or the study of past climate prior to instrumental records, allows scientists not only to collect evidence of past climate conditions, such as drought, but also provides them with a means to investigate the climate processes underlying these conditions.
