Pt Arena Glider Line 56.7

Current Glider Position

Current Glider Track and Position

Track (blue line) and current location (red dot)

A glider continuously transects CalCOFI Line 56.7 between Pt. Arena and 500 km offshore to the southwest. Gliders have been collecting observations along this track since 2019. The map on the right shows the current location of the active glider.The active mission data is plotted below and data from both the active and completed missions is available for download.

Active Mission Plots

Plot Details: The contour plots below are updated every 4 hours and display water temperature, salinity, chlorophyll flourescence and acoustic backscatter from the surface to 500 meters depth. The top plot for each variable is the most recent glider transect. The dates on the top axis of plot provide a reference to the start and end time of that stretch of data. The x-axis on each plot represents the distance along the track and indicate the glider’s direction (towards or away from shore). Learn more about how to interpret glider contour plots
