One of Europe’s worst famines likely caused by devastating floods
Europe’s Great Famine of 1315–1317 is considered one of the worst population collapses in the continent’s history. Historical records tell of unrelenting rain accompanied by mass crop failure…Now, new research using tree ring records confirms the historical data, showing the years of the Great Famine were some of Europe’s wettest.

Melting ice may change shape of Arctic river deltas
Thawing ice cover and easily erodible permafrost may destabilize Arctic river deltas, according to new research. A new study in the AGU journal Geophysical Research Letters finds sea ice and permafrost both act to stabilize channels on Arctic river deltas.

Western droughts caused permanent loss to major California groundwater source
According to new research, the San Joaquin Valley aquifer in the Central Valley shrank permanently by up to 3 percent due to excess pumping during the sustained dry spell.

Permafrost loss dramatically changes Yukon River chemistry
Permafrost loss due to a warming Alaska is leading to changes in the chemistry of the Yukon River Basin with potential global climate implications. This is the first time a Yukon River study has been able to use long-term continuous water chemistry data to document hydrological changes over such an enormous geographic area and long time span.

Large precipitation events critical in replenishing groundwater resources
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.

Waiting for the weather to clear
On Sunday afternoon, we headed back to Newport. The scientists and crew were closely watching the weather to see when we will be able to head back on the water. The down time gives Goni and his team some time to filter water samples that were collected from the Newport Hydrographic Line on Friday. The samples are one piece of a larger project trying to figure out how small coastal rivers are influencing coastal ocean productivity during the winter.

High water tables can be a boon to crop yields
High water tables can be a bane to crop yields, compelling many farmers to drain their fields so their crops don’t drown when it rains.
But a high water table may not always be a bad thing. A new study shows it is actually a boon for some fields and during certain times of the growing season, casting light on opportunities for improving yield efficiency to meet global food demands.
