Short field videos
As part of an NSF funded project to estimate benthic productivity across the Aleutians, benthic chambers were placed within kelp forests, areas devoid of understory algae with urchins, and urchin barrens. Here, a chamber placed within a kelp forest off Unalaska Island is broken down 24+ hours after deployment.
Early June 2016 pelagic red crabs Pleuroncodes planipes appeared off Point Loma, San Diego.
To get an idea of the top-down effects of fish predators like sheephead Semicossyphus pulcher and rock wrasse Halichoeres semicinctus in rhodolith beds at Catalina I tethered urchins in rhodolith and crushed rhodolith and recorded survivorship, this is sped up video from one of the trials.
This mantis shrimp Hemisquilla ensigera californiensis likely takes advantage of the abundant epi-/infauna like molluscs and bivalves that live within and under the rhodolith beds at Santa Catalina Island.
Here is a rhodolith individual taken from a rhodolith bed in southern Spain.
In a rhodolith bed off southern Spain, Dr. Diana Steller shows a rhodolith with a scallop on its surface.
In southern Spain we were able to take a dive in a Posidonia oceanica meadow during the IV International Rhodolith workshop that was held in Granada, Spain in 2012.
California sea lions Zalophus californianus are some of the most agile organisms in the water, we were surrounded at Santa Catalina Island during a receiver retrieval dive.
Curious harbor seals Phoca vitulina are ubiquitous off Hopkins Marine Station in Pacific Grove, CA.
A sea nettle Chrysaora fuscescens moves through a kelp forest off Carmel, CA.
Surrounded by Chrysaora fuscescens sea nettles while diving to install acoustic receiver moorings in Monterey Bay.
While collecting purple urchins for a tethering survivorship study in different habitats, I ran into a California moray that came out to show this is its territory.
