New PORTS Dedicated in Charleston, S.C. [What's New]

This item was filled under News
Charleston harbor, South Carolina, is home to the nation's 23rd Physical Oceanographic Real-Time System (PORTS®). This NOAA system provides real-time information that determines bridge clearance measurements from special air gap sensors, as well as water level and meteorological information from long-term tide stations, providing users with critical data when transiting the harbor.

Officials from NOS's Center for Operational Oceanographic Products and Services (CO-OPS) and the South Carolina State Ports Authority dedicated the new system on June 27.

Location of upwelling in Earth’s mantle discovered to be stable

This item was filled under Climate
A new study shows that large-scale upwelling within Earth's mantle mostly occurs in only two places: Beneath Africa and the Central Pacific. These upwelling locations have remained remarkably stable over geologic time, despite dramatic reconfigurations of tectonic plate motions and continental locations on the Earth's surface. The study describes a plate tectonic "quadrupole," which defines two points of "net convergence" and two points of "net divergence" of tectonic plate motions....
