Ocean Science:

1. Route for Upwelled Kuroshio Waters into East China Sea Shelf

A simple algorithm obtains short-term variations in upwelling, which show that the subsurface Kuroshio waters can upwell directly into the East China Sea shelf under the advection of the Kuroshio.


Climate Change:

1. Population and Climate Change Point to Future Water Shortages

A new study suggests that reductions in agricultural water use will probably play the biggest role in limiting future water shortages.


2. The Urban Dry Island Effect

A study of the Yangtze River Delta shows how urbanization dries out the atmosphere.


3. Ice-Free Arctic Summers Could Happen on Early Side of Predictions

A new study predicts the Arctic Ocean will be ice-free in summer by mid-century.


4. Extending the Record of Surface Melt on the Larsen C Ice Shelf

The first use of Advanced Scatterometer radar data to determine melt duration on an Antarctic ice shelf shows the season has decreased by up to 2 days per year during the extended 21st century record.


5. Humming Ice Shelf Changes Its Seismic Tune with the Weather

Seismic waves resonating within the upper layers of the Ross ice shelf could help scientists monitor the Antarctic melt season and understand factors that could lead to sudden ice shelf collapse.


Hazards & Disasters:

1. Observing Volcanoes from Space

The first multidecadal, satellite-based study of Latin America’s most active volcanoes could help researchers better predict eruptions.


2. Varying Impact of Earthquake-and Monsoon-Induced Landslides

Using nearly 50 years of satellite data and records stretching back millennia, scientists determine the relative frequency—and the erosional power—of monsoon- and earthquake-induced landslides in Nepal.


3. Assessing the Benefits of Improved Space Weather Forecasting

A new framework assesses the economic impact of space weather on power distribution networks and the supply of electricity.


Natural Resources:

1. Apollo May Have Found an Earth Meteorite on the Moon

The meteorite may have been blasted off of Earth during an impact, mixed with lunar rocks, and brought back to Earth 4 billion years later by astronauts.


Space & Planets:

1. First Privately Developed Lander En Route to the Moon

The lander, built by an Israeli company, will survive on the surface for just a few days. It will capture magnetic field data and conduct an experiment with a lunar orbiter.


2. Plasma Density Distribution in Mercury's Magnetosphere

A new measurement of plasma density distribution in Mercury’s magnetosphere obtained from observations of field line resonance events provides necessary constraint for many planetary science issues.


3. A Target Before Shooting Ryugu

The asteroid's rough surface surprised Hayabusa2's mission scientists. So they pulled out their spare gun and shot an "asteroid" at home first.


4. Can Moderate Space Weather Have Major Impacts?

Pipeline corrosion is an example of why we need better awareness of how long-term exposure to moderate space weather may have significant economic impact by slowly degrading vulnerable systems.
