A colorful sunrise appears over the horizon of a calm ocean offshore of Melbourne, Florida. USGS Scientist RC Mickey collects data for location and elevation of sea turtle crawls and associated beach profiles this stretch of coastline.

The water level continues to slowly rise in Halema‘uma‘u, drowning many of the small rocks that were exposed in the center of the pond. Ripples across the water surface were also evident today.

Anna McKee of the SAWSC, Norcross, GA, prepares DNA from water samples to test for bacteria that indicate sources of fecal contamination. Understanding the sources of contamination can help target mitigation and outreach efforts.

 Research scientist Meagan Gonneea and USGS intern Angela Trejo survey the Jones River in Kingston, MA. Removal of a dam across the Jones River began July 15, 2019, as a first step to restore river habitat, which is particularly critical for herring passage from the sea to inland lakes for spawning.
