Led by Dr. Julie Loisel, these geography undergraduates’ unforgettable summer trip was actually quite cold.

The flowers mingle beautifully in a late-summer breeze along the west patio of the Iowa Memorial Union, the dark crimson petals of bee balm providing a perfect contrast to the golden blossom of the black-eyed Susan and the orange glow of the blanket flower.

Building on a century of hydroscience research, the University of Iowa enters a new era of activity aimed at solving Earth’s biggest environmental issues.

A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States.

For angiosperms — or flowering plants — one of the most important decisions facing them each year is when to flower. It is no trivial undertaking. To flower, they must cease vegetative growth and commit to making those energetically expensive reproductive structures that will bring about the next generation.

Data acquired by the U.S. Geological Survey on the U.S. Atlantic Margin in August 2018 reveal new information about the distribution of gas hydrates in the sector stretching from the upper continental slope to deep water areas offshore New Jersey to North Carolina.

As anticipated, Hurricane Florence resulting in monumental rainfall totals, particularly across southern and eastern North Carolina.  This past week’s rainfall totals are depicted in Figure 1, derived from the NOAA/National Weather Service Advanced Hydrologic Prediction Service (AHPS).  Widespread totals exceeded 10” across most of southern/eastern North Carolina and far eastern South Carolina, with maximum rainfall of more than 20” along and within a few counties of the Atlantic Coast.

Each year, fishermen harvest more than $500 million worth of Atlantic sea scallops from the waters off the east coast of the United States. A new model created by scientists at the Woods Hole Oceanographic Institution (WHOI), however, predicts that those fisheries may potentially be in danger. As levels of carbon dioxide increase in the Earth’s atmosphere, the upper oceans become increasingly acidic—a condition that could reduce the sea scallop population by more than 50% in the next 30 to 80 years, under a worst-case scenario.  Strong fisheries management and efforts to reduce CO2 emissions, however, might slow or even stop that trend.

Artificial light at night also makes guppies more courageous during the day, according to a behavioural study led by researchers from IGB and the Max Planck Institute for Human Development. Exposing fish to artificial light at night, not only made fish more active during the night, but also made them emerge quicker from hiding places during the day, which could increase their exposure to predators. Nocturnal lighting, however, did not affect their swimming speed or social behaviour during the day.

In the spring of 2018, a centuries-old ship washed up on the shore of Guana Tolomato Research Reserve in Ponte Vedra Beach, Florida.
