Domoic Acid

If phytoplankton capable of making DA are common in open ocean phytoplankton blooms, do they express this gene and make DA? There have been few measurements published related to the expression of the gene for DA in open ocean phytoplankton. Wells and coworkers [Wells et al., 2005] are one of the few groups who have studied Pseudonitzschia in the open ocean. They indicate that DA plays an important role, together with copper, in ensuring that Pseudonitzschia can survive under very low iron conditions in the open ocean. “This system may explain why Pseudonitzschia spp. are persistent seed populations in oceanic HNLC regions, as well as in some neritic regions. Our findings also indicate that in the absence of an adequate copper supply, iron-limited natural Pseudonitzschia populations will become increasingly toxic.” (p. 1998). We know from studies of Pseudonitzschia strains from coastal waters that they are more likely to make DA when iron-stressed than when growing under iron-replete conditions: “Our findings suggest that DA production during exponential growth of these two toxigenic Pseudonitzschia species is directly induced by Fe-deficient or Cu stress conditions and that 95% of this DA is actively released into the medium.” (p.
515) [Maldonado et al., 2002].

Fish kills in Australia

Summer has set in Queensland, Australia and this is resulting in fish kills due to low Dissolved Oxygen.

Biodiesel from Diatoms



"Note that an algal oil slick has now appeared on top of the water, as the oil-laden diatoms begin to leak oils. Oily foams, are now forming in this oil-production photobioreactor.

Note the large oily bubble that has formed at the water line at the lower right corner."

Mr Patrick Ward of Richmond, VA, USA has also obtained some biofuel from Diatoms.
He has been working on this since 2006.

Biofuels: Hope or Hype?

http://solveclimate.com/blog/20091202/biofuels-hope-or-hype

"Biofuels aren’t new. Henry Ford designed his 1908 Model T to run on ethanol from corn, but Standard Oil and its fossil fuel cohorts, seeing the threat biofuels presented to their business, lowered their prices and drove biofuels out of the marketplace."

Now we know why petrol has been so cheap all these years.

Carbon must be sucked from air, says IPCC chief Rajendra Pachauri

Carbon must be sucked from air, says IPCC chief Rajendra Pachauri

...

"Dr Pachauri raised the prospect of so-called geo-engineering, whereby carbon dioxide is actively stripped from the atmosphere. A range of techniques have been proposed including seeding artificial clouds over oceans to reflect sunlight back into space, sowing the oceans with iron ore to boost plankton growth and using carbon capture and storage technology to fix emissions from power stations."
