Since 2000 the first Saturday in May is Snapshot Day in Santa Cruz. This is a big event where the Coastal Watershed Council trains groups of citizen scientists to collect water quality data on the streams and rivers that drain into the Monterey Bay National Marine Sanctuary, then sets them loose with a bucket of gear,…

Not always a death sentence
I’ve already written several times about seastar wasting syndrome (SSWS) and you’ve probably seen your share of photos of wasted, melting, self-mutilating stars. However, you may also be wondering about the current state of affairs regarding SSWS, and whether or not sea star populations have recovered at all since the outbreak began three years ago…
LiMPETS (but not so many limpets)
In recent years, citizen science has become a very important provider of biological data. This movement relies on the participation of people who have an interest in science but may not themselves be scientists. There is some training involved, as data must be collected in consistent ways if they are to be useful, but generally no…
The bloom is on
This week it has been very windy on the coast. As in hope-the-next-gust-doesn’t-arrive-while-I-am-still-holding-onto-the-door windy. Seriously, the other day I almost wrenched my shoulder when the wind caught a door I was walking through just as I opened it. I should have braced myself before opening that door. The wind also blows around dust and pollen, exacerbating everybody’s…
Seeing stars at Pigeon Point
This morning I drove up the coast to Pigeon Point. It was cold and very windy, and I was grateful to have decided to wear all of my layers. I don’t remember any cold mornings from last year’s low tides, which made me think that perhaps we’re returning to a more normal non-El Niño weather pattern. The…
A little less confounded now
So. Last week when I looked at my sand dollar larvae I wasn’t at all sure what to make of them. I thought that all of the offspring from one of the matings (F2xM1) were going south and didn’t know how much longer they would survive. The offspring from the other two matings seemed to be…
Surprise!
Yesterday I went over to the Seymour Center to talk to the person at the front desk about arranging a field trip visit for a class I’ll be co-teaching this summer. When I walked through the exhibit hall into the office wing there were a couple of staff members coming the other way down the hall,…
Confounded
Remember that one batch of sand dollar larvae that were looking weird on Monday? Well, they still look weird. In fact, all of the larvae looked the same yesterday as they did on Monday, which seems strange, considering how quickly they galloped through development for the first three weeks of larval life. It’s as though they’ve…
Dinner time!
The red-tailed hawk parents across the canyon are being kept busy by their hungry chicks. This year they have a trio of youngsters to feed–last year they successfully fledged two chicks–but apparently they’ve not had any trouble finding enough food for all three of them. If I had the luxury of staying home all day…
What are they up to?
These sand dollar (Dendraster excentricus) larvae that I’ve been raising will be 21 days old tomorrow, and they are still on the fast track. They’re developing much more quickly than any of the sea urchin cohorts I have raised. Some of them already have juvenile rudiments with tube feet visible. With the urchins (Strongylocentrotus purpuratus)…
