Hydrothermal vents and possible new species discovered in Gulf of California

The hydrothermal vents are located in the Pescadero basin and are unique both in their chemistry and appearance to other known hydrothermal vents, as they are the only ones currently observed to emit clear fluids as opposed to dark, smokey fluids associated with iconic “black smoker” vents.

Indigenous names

The largest of the new vent mounds, named Maija awi, sits midway between the JaichaMaa ‘ja’ag vent field, discovered by the same team during Schmidt Ocean Institute’s 2018 R/V Falkor expedition, and the Auka vent field, discovered during an expedition by the Monterey Bay Aquarium Research Institute (MBARI) in 2015.

Long Beach Scuba Show 2021 Cancelled

Last year, we told you that there was "no way to responsibly hold an event of this size with people from around the world for the foreseeable future." When we wrote that, we never would have guessed the "foreseeable future" would extend well over a year.

To bridge the gap, we are working on a resource for divers - for you. Information from our exhibitors with videos, specials, new products, travel and more.

Giant kelp (Macrocystis pyrifera) is a species of kelp (large brown algae)

Kelp forests help the climate

Kelp is an ecologically and economically important foundation species in California, where forests line nutrient-rich, rocky bottom coasts. It also might alleviate acidification caused by too much atmospheric carbon being absorbed by the seas.

A new interdisciplinary analysis of giant kelp in Monterey Bay off the coast of California shows that near the ocean’s surface, the water was less acidic, suggesting the kelp canopy does reduce acidity.

Due to their unique position relative to the eastern Pacific current, or the California Current, the Channel Islands off California’s coast receive an ideal amount of nutrients and water circulation for optimum growth of California giant kelp. This colonial algae forms forests over the rocky reefs and walls surrounding the islands, and act as one of the world’s most productive marine ecosystems.

2020 Long Beach Scuba Show Cancelled

We considered moving the 2020 show to later in the year, but ultimately decided that postponing the show still held too much uncertainty. The wellbeing of everyone under our roof is our primary concern, and there's no way to responsibly hold an event of this size and with people from around the world for the foreseeable future.

If you have already purchased tickets for the 2020 Scuba Show, you have two options. Please email us to let us know your preference:

Northern California: A Dive Off the American Wild West Coast

Warm rinse water sloshed in the jug as my car hugged a sharp turn on California’s Pacific Coast Highway. I looked left at the mighty Pacific Ocean, the cliffs tumbling to the sea dotted by rugged pinnacles, stretching farther up the coast than the jam band solo currently playing out of the car speakers. Deep blue, favorable conditions all week, minimal swell, no-wind forecast—only unpredictable visibility could affect the diving today.

Ships and blue whales in conflict off California

A new study in the journal Plos One has revealed blue whales assemble for long periods in the busy shipping lanes off California, raising concerns about collisions between vessels and the endangered cetaceans.

“It’s an unhappy coincidence,” said study leader Ladd Irvine, a marine mammal ecologist at Oregon State University. “The blue whales need to find the densest food supply. There’s a limited number of those dense places, and it seems as though two of the main regular spots are crossed by the shipping lanes.”
