Currents_Historic_Stations
Layer represents the geographic locations that are no longer active at
which current (water velocity) observations were collected. Generally, "currents" are defined as a horizonal movement of water. Currents may be classified as tidal and nontidal. Tidal currents are caused by gravitational interactions among the sun, moon, and earth and are part of the same general movement of the sea that is manifested in the vertical rise and fall, called tide. Nontidal currents include the permanent currents in the general circulatory systems of the sea, as well as temporary currents arising from more pronounced meteorological variability. Most stations with current observations provide readings every 6 minutes. Each year, CO-OPS measures currents at many coastal locations in order to provide accurate tidal current predictions for the maritime community. These data sets typically range from one to three months in length and at most locations, data are available throughout the water column. These data contain the raw current measurements taken during these surveys, which date back to 1997. Data
from formerly active (real-time) stations also can be found here. More information can be found at
