In spring 2015, MBARI researchers discovered a large, previously unknown field of hydrothermal vents in the Gulf of California, about 150 kilometers (100 miles) east of La Paz, Mexico.
Lying more than 3,800 meters (12,500 feet) below the surface, the Pescadero Basin vents are the deepest high-temperature hydrothermal vents ever observed in or around the Pacific Ocean.
They are also the only vents in the Pacific known to emit superheated fluids rich in both carbonate minerals and hydrocarbons. The vents have been colonized by dense communities of tubeworms and other animals unlike any other known vent communities in the in the eastern Pacific.
Like another vent field in the Gulf that MBARI discovered in 2012, the Pescadero Basin vents were initially identified in high-resolution sonar data collected by an autonomous underwater vehicle (AUV). MBARI’s yellow, torpedo-shaped seafloor-mapping AUV spent two days flying about 50 meters above the bottom of the Basin, using sound beams to map the depth and shape of the seafloor.
The AUV team, led by MBARI engineer David Caress, pored over the detailed bathymetric map they created from the AUV data and saw a number of mounds and spires rising up from the seafloor. Data from the AUV also showed slightly warmer water over some of the spires, which implied that they might be active hydrothermal-vent chimneys. A team of geologists led by David Clague then used a tethered underwater robot, the remotely operated vehicle (ROV) Doc Ricketts, to dive down to the seafloor, fly around the vents, and collect video and samples of rocks and hot water spewing from the chimneys.



Analysis of the impact of the terrible 2010 BP Gulf of Mexico oil disaster (picture right) and a study of peat bogs, shows climate scientists may be wrong to claim such “greenhouse gases” can cause catastrophic long term impacts.
We’ve seen this already in the
And it is a strong and constant activity, re-enforced by environmental stressors.
But according to an expert in the field of polar observations, those conclusions appear to be “
More specifically, a team led by Ala Khazendar of NASA’s Jet Propulsion Laboratory has found that the ice is melting so fast that the shelf will be gone before 2020. Presumably, that’s the good news.

Mawson Station, the longest continuously operated outpost in Antarctica, has relied on access to a nearby bay, which is increasingly becoming more complicated by sea ice blocking the way.
