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.

Heart Me Up

In defense of Valentine’s Day

 

“be(ing) of love (a little) more careful”—e.e. cummings

Wednesday (Feb. 10) is Ash Wednesday, when Lent begins. Friday (Feb. 12) is Lincoln’s 207th birthday. Sunday is Valentine’s Day. On Ash Wednesday, with foreheads marked with a cross of ashes, we hear the words, “From dust thou art and unto dust thou shalt return.” Reminding us that our bodies, made of matter, will remain here on Earth when we are called back. It is our Soul that will take us home again. Lent offers us 40 days and nights of purification in preparation for the Resurrection (Easter) festival (an initiation) and for the Three Spring Festivals (at the time of the full moon)—Aries, Taurus, Gemini. The New Group of World Servers have been preparing since Winter Solstice. The number 40 is significant. The Christ (Pisces World Teacher) was in the desert for 40 days and 40 nights prior to His three-year ministry. The purpose of this desert exile was to prepare his Archangel (light) body to withstand the pressures of the Earth plane (form and matter). We, too, in our intentional purifications and prayers during the 40 days of Lent, prepare ourselves (physical body, emotions, lower mind) to receive and be able to withstand the irradiation of will, love/wisdom and light streaming into the Earth at spring equinox, Easter, and the Three Spiritual Festivals. What is Lent? The Anglo-Saxon word, lencten, comes from an ancient spring festival, agricultural rites marking the transition between winter and summer. The seasons reflect changes in nature (physical world) and humanity responds with social festivals of gratitude and of renewal. There is a purification process, prayerfulness in nature and in humanity in preparation for a great flow of spiritual energies during springtime. Valentine’s Day: Aquarius Sun, Taurus moon. Let us offer gifts of comfort, ease, harmony, beauty and satisfaction. Things chocolate and golden. Venus and Taurus things.
