The coast from Monterey Bay to the Mexican border is experiencing what's commonly known as a red tide event.

That might be an understatement. Moorings and piers with oxygen sensors give us a good picture of the high frequency changes in dissolved oxygen concentration from day-to-day. Red tides, which stretch from Baja California up the coast to Los Angeles, have been observed since the early 1900s and can last from a few days to a couple of months.

While the water may appear red/brown, it is generally not a public health concern. When conditions align, they multiply quickly. As you can see on the tide chart, the highest tide of 5.77ft was at 7:24 am and the lowest tide of -0.1ft was at 2:22 pm. A red tide is causing the nighttime surf to light up in a striking blue color along parts of the Southern California coast. The recent red tide is the strongest in at least a quarter-century, and perhaps the largest on record, Latz said, lasting more than a month and stretching from Los Angeles south to Acapulco. Luminous waves are also a frequent occurrence at Orange County beaches. At this point, the sensor may or may not still be recording and it could also be fouled since it has been out there for several months. Figure 48. Video 1.

These “red tides,” as they are often called, are not unusual in Southern California, and most California natives have seen bioluminescence at some point in their lives. “In May 2018, the red tide lasted only a few days, while the October 1995 red tide lasted a month. 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. 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. and Lingulodinium polyedra (Fig. are formed by toxin producers. During the day, it's best to avoid places that are affected by a red tide. Figure 30-34. The SeapHOx registered a high oxygen spike in early April just before the battery on the modem died. 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. This year, the red tide stretches all the way from Baja California to Santa Barbara.” Most Read Source: Michael Latz, UCSD/SIO. 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 (Fig. (Left) Precipitation percent difference from average (%) from March 4th, 2020 to May 2nd, 2020. Beachgoers in California were treated to a rare spectacle this week: glowing tides. Beachgoers in California were treated to a rare spectacle this week: glowing tides. Massive red tide events only happen once every several years. Like most phytoplankton, they also grow well when temperatures are warm, a factor which further contributes to the stratification. This is a function of high respiration rates of bacteria as well as nighttime cellular respiration by the algae. This has led to the term “red tide,” but widespread use of this term to describe a variety of blooms around the world is confusing. Nitrate (anthropogenic and natural) and phosphate as well as regenerated forms of nitrogen, such as urea and ammonium, could have helped to keep this bloom cranking, especially as waters warmed and stratification set in. 37-40) and/or toxins are to blame.

The effects of red tide at night along the coast of Southern California Every so often, our coastal waters take on a peculiar shade of rusty brown or burnt burgundy – indicating what is known as a “red tide”. At its best, California's red tide can be as mesmerizing as the Northern Lights' winter dance, the summertime glow of fireflies, or the simple pleasure of a glow stick from the dollar store. In California the majority of red tides are not caused by species that producedeadly toxins such as domoic acid andthe paralytic shellfish poisoning toxins. effluent) to the Pacific Ocean via the Point Loma Ocean Outfall (PLOO; Fig. The California Underwater Glider Network (CUGN) has five active Spray underwater gliders deployed off California's coast.

This current one stretches from Baja California, Mexico up to Santa Barbara. If the species is red-tinted, it can make the water look red. Figure 47.

Early on, it may be that nutrients from runoff sustained active growth of the, bloom but were likely not the cause of the bloom considering it was already developing further offshore away from the influence of terrestrial inputs. Many algae produce toxins that both taint the water and become airborne when they are at the surface. “Its like when a wave breaks or dolphins swim through, or a boat goes through the red tide, you will see this cool neon blue light.

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 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.
