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.

Week of Festivals: Full Moon, Lantern Festival, Purim, Holi

It is a week of many different festivals along with a full moon, all occurring simultaneously. Thursday Chinese New Year celebrations end with the Lantern Festival (at full moon). Thursday is also the Pisces Solar festival (full moon), Purim (Jewish Festival) and Holi (Hindu New Year Festival). Sunday, March 8, Daylight Saving Time begins at 2 a.m. The festival of Purim celebrates the freedom of the Hebrew people from the cruel Haman (a magistrate) seeking to destroy them. Esther, the Queen of Persia, who was secretly Jewish, saved her people from death. The sweet cookie hamentaschen celebrates this festival. Friday, March 6, is Holi, the Hindu Spring Festival celebrated after the March full moon. Bonfires are lit the night before, warding off evil. Holi, the Festival of Colors, is the most colorful festival in the world. It is also the Festival of Love—of Radha for Krishna (the blue-colored God). It is a spring festival with singing, dancing, carnivals, food and bhang, a drink made of cannabis leaves. Holi signifies good over evil, ridding oneself of past errors, ending conflicts through rapprochement (returning to each other). It is a day of forgiveness, including debts. Holi also marks the beginning of New Year. At the Pisces Solar festival we recite the seed thought, “We leave the Father’s home and, turning back, we save.” Great Teachers remain on Earth until all of humanity is enlightened. The New Group of World Servers is called to this task and sacrifice. Sacrifice (from the heart) is the first Law of the Soul, the heart of which is Love. This sacrifice saves the world.

When looking for a bottle of something to have with dinner, Gewürztraminer 2012 is not the first wine to come to mind. Given the popularity of Chardonnay, Sauvignon Blanc, Merlot and Pinot Noir—to name but a few—Gewürztraminer sits low on the totem pole.
