New Findings Demonstrate Diversity of Red Algae Blooms

blog_slug_algeIron-Thirsty Algae Thwart Counter-Global Warming Plans
Blooms of red algae, which typically occur in coastal waters, are associated with the poisoning of ocean water and the destruction of coastal ecosystems. A new study finds that blooms of this deadly organism can also flourish out in the open ocean and can wreak havoc if the ocean’s iron levels increase.

This finding, reported in the Proceedings of the National Academy of Sciences, is relevant to scientists because it poses a severe ecological side effect to proposed plans to combat global warming. The authors of the paper, which include several UC Santa Cruz professors, warn that fertilizing the ocean with iron to combat the pressures of global warming, could irrevocably damage the ecosystems of the world’s oceans and disrupt the global food chain.

The microcosms that flourish in high-iron environments are diatoms belonging to the genus Pseudo-nitschia. When these organisms reproduce rapidly and create a bloom, significant amounts of a neurotoxin they release, domoic acid enters the food chain and poisons fish, birds, and aquatic mammals.

The discovery that Pseudo-nitschia thrive in iron-rich waters poses a significant setback to talks in the scientific community about potentially fertilizing ocean waters with iron to promote the growth of other algae that absorb carbon dioxide. However, as coauthor of the report and director of Moss Landing Marine Laboratories Kenneth Cole commented in the UCSC press release for the findings, “this work definitely reveals a wrinkle in those plans” because of the algae’s potential to destroy the ocean’s ecosystems and subsequently diminish the terrestrial food chain.

Mary Silver, the lead author of the study and professor of ocean sciences at UCSC, conducted research on the algae throughout the Pacific Ocean and adds, “to do iron enrichment on a large scale could be dangerous because, if it causes blooms of Pseudo-nitschia, the toxin might get into the food chain, as it does in the coastal zone.”

Though he thinks nitrogen fertilization of the oceans would be dangerous and unwise, Cole believes that all people, scientists and citizens alike should continue to combat global warming. “In light of these findings, we should redouble our efforts to reduce carbon emissions, the primary culprit for ocean ecosystem damage worldwide,” he said.

Spring Triangle: Three Spring Festivals—Aries, Taurus, Gemini

The Spring signs Aries, Taurus and Gemini constitute a triangle of force that sets the template for the nine signs that follow and the template for the entire year (Spring 2015 - Spring 2016) ahead. Aries initiates new ideas, Taurus stabilizes the new thinking of Aries and Gemini takes the initiating stabilized ideas of Aries/Taurus and disperses them to all of humanity. It is in this way that humanity learns new things, with the help of Mercury, the messenger. As Spring unfolds, three elements emerge: the Fire of Aries (initiating new ideas), the Earth of Taurus (anchoring the ideas of God through Mercury) and the Air of communicating Gemini. These three signs/elements are the Three Spring Festivals. They are the “triangle of force” forming the template (patterns) of energy for the upcoming new year. After these three we then have the soothing, calming, warming, nurturing and tending waters of the mother (Cancer). Cancer initiates our next season under the hot suns of summer. Planets, stars and signs create the Temple of Light directing humanity towards all things new. March 29 is Palm Sunday, when the Christ, World Teacher, was led into Jerusalem (City of Peace) on a donkey (humility). Palms waving above His head, signified recognition of the Christ’s divinity. Palm Sunday is the Sunday before the Easter (Resurrection Festival). Palm Sunday begins Holy Week, the week of capture, imprisonment, passion, sacrifice, crucifixion, death and resurrection of the christ. All events in the Christ’s life represent events (initiations) that humanity experiences through many lifetimes. We turn our attention to these holy events this week. Their concepts portray and reveal to us greater spiritual understanding. Then, Aries, the “light of life itself” shines through us.

A hike that’s across from Waddell Beach. I didn’t realize you could go across the highway and do a super simple loop, and it’s beautiful. You can see the coastline. Liz Porter, Santa Cruz, Community Outreach
