Thanks to Amy Bohorquez' Biology class at Laney College for field work on October 24th!

10-24-species list: Sampled from 2 places: Lake Merritt Boating Center dock (Carlton site G) and the amphitheater beach area (Carlton site C). I brought organisms from dock to the class meeting place by amphitheater green pedestrian bridge.

Water quality measurements were taken from the green bridge over the entrance to Lake Merritt Channel: Temperature 20 degC top/22 degC bottom; Salinity 27 ppt top/bottom; Secchi depth >1.25 m; Dissolved oxygen 7 ppm top/8 ppm bottom; pH 7 top/7 bottom; 2:30 p.m.; ebb tide.
