In the spirit of June as Pride month, I thought it would be fun to showcase the colors of the intertidal. All of these are photos that I’ve taken at various sites since January 2019. Here goes! Red, including pink Orange Yellow, including gold and ochre Green Blue Purple And there you have it! Happy…

Algae at Pigeon Point
The annual Snapshot Cal Coast period is scheduled to coincide with the best midsummer low tides, to maximize opportunities for people to get out and blitz the intertidal. The whole idea of Snapshot Cal Coast is to document as much biodiversity as possible, to render a comprehensive account of what our coastal and nearshore biota…
Counting critters
Professor Emeritus John Pearse has been monitoring intertidal areas in the Monterey Bay region since the early 1970s. Here on the north end of Monterey Bay, he set up two research sites: Opal Cliffs in 1972 and Soquel Point in 1970. These sites are separated by about 975 meters (3200 feet) as the gull flies….
Home, it’s where I want to be
All semester I’ve been taking my Ecology students out in the field every Friday. We’ve visited rivers, forests, natural reserves, endemic habitats, and fish hatcheries–none of which fall into my area of expertise. This year I have several students interested in various aspects of food production, natural/holistic health practices (which sometimes conflict with actual science!),…
Green
The marine macroalgae, or seaweeds, are classified into three phyla: Ochrophyta (brown algae), Rhodophyta (red algae), and Chlorophyta (green algae). Along the California coast the reds are the most diverse, with several hundred species. The browns have the largest thalli (the phycologists’ term for the bodies of algae), including the very large subtidal kelps as…
Snow in July
The Sierra snowpack is California’s largest single reservoir of fresh water, accounting for 1/3 of the state’s water supply1. A state with a mediterranean climate, such as California, receives precipitation only during the short rain/snow season. During years of drought, when the average Californian frets about how little rain is falling, state water managers are…
Puzzling
The marine macroalgae are, as a group, the most conspicuous organisms in the intertidal. Yet, most tidepool explorers dismiss them as “seaweeds” and move on to the next thing, which they hope is somehow more interesting. This is akin to visiting the jungles of Brazil and not paying attention to the lush foliage that defines…
They deserve a prettier name than “rockweed”
As spring arrives in full force, the algae are starting to come back in the intertidal. The past two mornings I went out on the low tides to look for something very specific (which I did find–more on that later) and noticed the resurrection of the more common red algae. So early in the season the…
Beginnings and leavings
A few days ago I was in the intertidal with my friend Brenna. This most recent low tide series followed on the heels of some magnificently large swells and it was iffy whether or not we’d be able to get out to where we wanted to do some collecting. Our first day we went up…
Simply green
A few days ago I told my friend Brenna that I’d hunt around in the marine lab for a bit of a green alga that she wants to press. I had a pretty good idea of where to look, only the animals I’d seen it on had been removed from the exhibit hall. I asked…
