In some places like Florida, “red tide” is used to describe a deadly harmful algal bloom of the species, Figure 16. Red tide is more common in February, March, August, and September, but it's impossible to predict precisely when it will happen, or how long it will last. At this point (5/05/20) the red tide has been present in the waters of So Cal’s beaches for more than 3 weeks. With so much biomass in the nearshore, however, it was therefore not a surprise that the beaches would become a spectacle of night-time bioluminescence, ).

That's also an interesting thing to see, but it won't make the water glow. For a limited time – doing her best Vegas impression on Southern California beaches from Point Loma to Huntington Beach – the luminous, the electric, the dazzling… Lingulodinium polyedrum! The substances that generate their bioluminescence are destroyed daily and regenerated just in time to cause a spectacular natural light show after dark. In California the majority of red tides are not caused by species that producedeadly toxins such as domoic acid andthe paralytic shellfish poisoning toxins. 6-7) and  Scripps Pier (Fig. Low oxygen conditions do not support life and therefore kill fish and benthic organisms. 1-5). Source: Halle Thompson, City of Carlsbad. A hypoxic or anoxic environment is not conducive to life, so fish and invertebrates in the water column and particularly on the ocean floor are quite susceptible when a bloom of this size degrades. Interestingly, 1) the presence of dead fish in aquaria using natural seawater artificially adjusted for high dissolved oxygen (John Hyde, UCSD/SIO) and 2) observations of mussels releasing from their shells (Melissa Carter, UCSD/SIO and Jimmy Fumo, UCSD/SIO) suggests that toxins could be involved. Many algae produce toxins that both taint the water and become airborne when they are at the surface. The SeapHOx registered a high oxygen spike in early April just before the battery on the modem died. This is a function of high respiration rates of bacteria as well as nighttime cellular respiration by the algae. When conditions align, they multiply quickly. and the phytoplankton were identified and photographed by, Collecting HABMAP water samples and net tows off Scripps Pier on May 4, Just about all phytoplankton can turn the ocean effectively red when they are growing fast and producing a lot of chlorophyll.

March was a very wet month and many have speculated on the role of rain in driving this year’s L. polyedra bloom. Phytoplankton, Lingulodinium polyedra, in a water sample taken on May 6th from Scripps Pier. 47-48).  Lingulodinium polyedra really took off in early April as the rains subsided and the freshwater likely contributed to making the surface waters more hospitable to L. polyedra, an alga that is known for preferring “stratified” conditions when the surface layer is less saline/dense than the bottom layer. While the water may appear red/brown, it is generally not a public health concern. What is especially unique this year is the incredibly high biomass that has led to very intense red/brown water (, ) and to some otherworldly light shows for weeks on end (, ). Reports of dead fish (e.g., Bass, Sardines, and Rockfish) and invertebrates (e.g., Snails and Sea hares) washing up along our coast from Los Angeles to San Diego beginning April 30th, 2020. “In May 2018, the red tide lasted only a few days, while the October 1995 red tide lasted a month.

The National Institutes of Health say the species that causes it can also cause "a peculiar, strong odor." While L. polyedra blooms do not require runoff to develop and indeed appear to have begun their rapid growth further out on the continental shelf away from the direct influence of discharge plumes, we cannot discount the effect nutrients from land could have in this situation.

A second concern is that there is a toxin associated with, known to occasionally cause harm in other regions and parts of the world and should be measured when a bloom becomes this prolonged.

The tide chart above shows the height and times of high tide and low tide for California. Figure 24. SCCOOS/SIO researchers will be analyzing these samples to try to better understand the causes and variability of the die-offs. A third concern is that when there is so much organic material in the water, the end-stage of the bloom will lead to hypoxic (low oxygen) or anoxic (no oxygen) conditions and hydrogen sulfide production from bacteria. The day-time max of oxygen production was an indication of high oxygen production by the bloom. The glow will seem more intense when the sky is darkest: on a moonless night or when the moon is new.

Like most phytoplankton, they also grow well when temperatures are warm, a factor which further contributes to the stratification. The red tide that created glowing bioluminescent waves along the California coast is breaking down, causing a rotten smell along the coast. The FWC Red Tide Status Line is now available for callers to hear a recording detailing Red Tide conditions throughout the state. Scientists in Ensenada, Baja are detecting yessotoxin in recent samples, indicating that the same may be occurring in southern California (Ernesto Garcia-Mendoza, CICESE).

However, one concern with, is that there are years of anecdotal reports from surfers and beach-goers claiming respiratory irritation from sea spray emerging near “red tide” water. Agua Hedionda Lagoon, Carlsbad on April 27. Figure 6-7. It is important to ascertain if low oxygen (, ) and/or toxins are to blame. A red tide is caused by a "bloom" of microscopic, red algae. No one seems to know for sure, but some scientists think it may be an adaptation that helps them startle potential predators.

Maybe it's because they're so close to the center of the entertainment industry, but it's almost as if those tiny sea critters know when to get ready for their performance. Figure X. The Scripps Ocean Acidification Real-time (SOAR) Monitoring Program, led by the Dr. Jennifer Smith Lab in collaboration with Dr. Todd Martz and Dr. Andrew Dickson, has been measuring long-term, high-resolution variability in pH and temperature in coastal La Jolla using state-of-the-art instrumentation on the Ellen Browning Scripps Memorial (EBSM) Pier at Scripps Institution of Oceanography since March 2012.Â, Measurement of dissolved oxygen (DO) was added in August 2018. If it's happening, you may want to see the ocean glow at night. In addition, light penetration into the water can be reduced by more than 95% by dense red tides, thereby affecting kelp growth, reproduction, and recruitment.Â, With the recent appearance of dead fish and invertebrates on beaches throughout Orange County and San Diego, particularly near semi-enclosed lagoons, it is clear that the bloom is causing harm (, ).

Todd Martz, UCSD/SIO, also has a SeapHOx unit moored in the Agua Hedionda Lagoon near Carlsbad Aquafarm and is measuring for a suite of ocean acidification variables including oxygen. Another factor is that newly upwelled water in California can also be low in oxygen and amplify the problem.

An easy way to find out whether one is going on is to search for local news about red tide in California. Interestingly, 1) the presence of dead fish in aquaria using natural seawater artificially adjusted for high dissolved oxygen (John Hyde, UCSD/SIO) and 2) observations of mussels releasing from their shells (Melissa Carter, UCSD/SIO and Jimmy Fumo, UCSD/SIO) suggests that toxins could be involved.

This suggests that some fraction of the population may be sensitive to these aerosols. This effect is amplified in semi-enclosed bays and lagoons with little exchange with the ocean and reduced mixing with the atmosphere will experience even lower oxygen. Figure 15.

It was a fairly typical mixture of microalgae for this time of year when upwelling of deeper water is delivering nutrients to the well-lit surface layer.
