Red-breasted Nuthatch in fall feeding mode

This Red-breasted Nuthatch was part of a small flock busily feeding in an evergreen tree in the old campground next to the Bay Trail on October 15th.  Notice the bird’s legs in the first two photos.  It looks like it is standing on  long stick-like legs, which is an illusion.

Environmentalists sink Nautilus data center

The proposal by Nautilus Data Technologies to set up a water-cooled data storage facility at Alameda Point was soundly rejected by the Alameda City Council on June 18.  The facility would have pumped over 14 million gallons of water a day through its facility to cool computer servers.  The company said water cooling is better for the environment than existing air conditioning technology.  But by the time the environmental community was finished weighing in, it was clear that the Nautilus once-through cooling system would have replaced one problem by creating a new one.

The screen on the intake pipe underneath Pier 2 sounded good, until you consider that all the water coming out the other end in the Bay would have been filtered water that would have upset the natural ecological balance.  Marine life would have been pasted against the intake screen and periodically scraped off.  Tiny organisms would have made it through the screen and potentially been killed by the heat.  The heated water at the point of discharge was another big concern, since warming water is one of the conditions in which toxic algae blooms occur.

Below are excerpts from letters sent by environmental groups to the city council and excerpts of public comments at the meeting.  Thank you to all who spoke up for the natural world and our fragile Bay ecosystem. Continue reading “Environmentalists sink Nautilus data center”

10 reasons why data center should change water cooling pipe location

Open Letter to Mr. James Connaughton
Chief Executive Officer
Nautilus Data Technologies

Dear  Mr. Connaughton,

The Alameda City Council has granted you approval of moving forward with your data storage facility at Alameda Point.  Please reconsider the route for discharging warm water from the cooling system.  Instead of heading south under the Bay Trail and through the harbor near the ferry maintenance facility, send the water discharge pipe north to the Oakland Estuary.

As someone who was instrumental in protecting large tracts of the Pacific Ocean during your tenure as environmental advisor to President George W. Bush, I believe the alternative route will appeal to your marine conservation values. Continue reading “10 reasons why data center should change water cooling pipe location”

Great Egret stalks a lizard

Great Egrets are commonly seen wading along a shoreline, in marshes and wetlands waiting for fish to come near before catching them with a quick thrust of its bill.

Great Egrets primarily eat small fish.  However, their diet can also include reptiles such as lizards, amphibians, birds, small mammals, shrimp, worms, dragonflies, beetles, water bugs, and grasshoppers.

This particular Great Egret decided to stroll into the old campground at Alameda Point in search of food.  It walked slowly up to a Rosemary bush and stood there for about five minutes, occasionally making slight head movements, before plunging its head into the bush to catch a lizard.

After holding the lizard in its bill for a few minutes, it gulped down the lizard and proceeded very slowly to another bush.

Osprey Family Thrives in Face of Adversity

Ospreys returned again this year to nest at Alameda Point’s Seaplane Lagoon.  But midway through the rearing process, the female became the sole provider and protector of her three chicks, after the male became entangled in fishing line.  Such osprey single parenting is unheard of.

Bottlenose dolphins visit Breakwater at Alameda Point

Bottlenose dolphins do not usually come to mind when thinking of wildlife at Alameda Point.  In fact, only three have been observed there in recent years, and those sightings were from canoes and kayaks.  But on July 24, two more dolphins were observed with two regulars meandering around next to Breakwater Island.  The standalone rock wall, or breakwater, is visible from Pier 3 where the USS Hornet Museum is berthed.

The first-time visitors were from Monterey Bay and identified by researchers with Golden Gate Cetacean Research (GGCR).  The group tracks the dolphins using a catalog of 91 dolphins showing individual markings, some with names. Continue reading “Bottlenose dolphins visit Breakwater at Alameda Point”
