You may notice a green, red or brown film on your favorite boating or swimming area in the summer. This coloring could mean that the water is affected by harmful algal blooms. Harmful algal blooms are an accumulation of tiny organisms known as algae and can release harmful toxins into the environment. If you see a bloom, avoid the area.

An HVO geologist photographs a small breakout covering the last stretch of exposed asphalt near the intersection of highways 130 and 137, just west of the current County lava viewing area.

A pahoehoe toe oozes onto the road, igniting the asphalt and nearby brush.

Lava burns through thick brush just north of Highway 130, near Kalapana Gardens.

Seining for fish in open water necessitates closing the seine quickly to avoid fish escape.  Closing the seine around a pole offshore accomplishes this objective in sampling.

Sampling juvenile common snook following passage of Hurricane Wilma October 2005.  Storm surge from hurricane is hypothesized to have facilitated recruitment of this sportfish to presumptive Tarpon Bay nursery grounds in the following 18 months.

Harrat Lunayyir basalt cinder cones and lava flows in Saudi Arabia seen from an aerial perspective. Deposits from the cinder cones cover nearby ridges and form fans at the base of the older non-volcanic ridge in the background. These well-preserved geomorphic forms indicate the relative youth of this northern part of the volcanic field.
