“…There is general agreement that HABs have increased in recent years (Herná ndez-Becerril et al, 2007; Corté s-Altamirano and Sierra-Beltrá n, 2008) and G. catenatumrelated blooms are no exception (Band-Schmidt et al, 2010); however, the increase in G. catenatum blooms along the Mexican Pacific coast does not appear to be related to anthropogenic activities. For example, extensive aquaculture and agriculture activities are present on the east coast of the Gulf of California, but there is no clear evidence that PST-producing blooms have increased due to pollution or nutrient runoff from these activities (Flores-Trujillo et al, 2009). Blooms of G. catenatum in the Gulf of California appear to be related to other environmental forcing factors.…”

Harmful algal blooms along the North American west coast region: History, trends, causes, and impacts

A B S T R A C TAlong the Pacific coast of North America, from Alaska to Mexico, harmful algal blooms (HABs) have caused losses to natural resources and coastal economies, and have resulted in human sicknesses and deaths for decades. Recent reports indicate a possible increase in their prevalence and impacts of these events on living resources over the last 10-15 years. Two types of HABs pose the most significant threat to coastal ecosystems in this ''west coast'' region: dinoflagellates of the genera Alexandrium, Gymnodinium, and Pyrodinium that cause paralytic shellfish poisoning (PSP) and diatoms of the genus Pseudo-nitzschia that produce domoic acid (DA), the cause of amnesic shellfish poisoning (ASP) in humans. These species extend throughout the region, while problems from other HABs (e.g., fish kills linked to raphidophytes or Cochlodinium, macroalgal blooms related to invasive species, sea bird deaths caused by surfactant-like proteins produced by Akashiwo sanguinea, hepatotoxins from Microcystis, diarrhetic shellfish poisoning from Dinophysis, and dinoflagellate-produced yessotoxins) are less prevalent but potentially expanding. This paper presents the stateof-knowledge on HABs along the west coast as a step toward meeting the need for integration of HAB outreach, research, and management efforts.Published by Elsevier B.V.

“…Oceanographic conditions in the tropical northwestern Pacific respond with different frequency and intensity to the variability of tropical weather events (Barron et al 2003, Goni et al 2006, Barron and Bukry 2007, Flores-Trujillo et al 2009, Staines-Urías et al 2009, Marchitto et al 2010, Pérez-Cruz 2013, Ricaurte-Villota et al 2013. The variability of marine productivity in the northwestern Pacific during the Holocene has been linked to the following: (1) the position of the subtropical high pressure system (e.g., Goni et al 2006, Pérez-Cruz 2013; (2) the relative position of the Intertropical Convergence Zone (ITCZ) and the North American Monsoon (e.g., Goni et al 2006, Staines-Urías et al 2009, Pérez-Cruz 2013, Ricaurte-Villota et al 2013; and (3) solar activity, an exogenous factor responsible for El Niño/La Niña-like atmospheric and oceanographic conditions (e.g., Marchitto et al 2010).…”

“…The few existing late-Holocene paleorecords from the tropical northwestern region of Mexico are for Guaymas Basin (Barron et al 2003, Goni et al 2006, Barron and Bukry 2007, Alfonso Basin (Staines-Urías et al 2009, Pérez-Cruz 2013, Ricaurte-Villota et al 2013, and Pescadero Basin (Flores-Trujillo et al 2009, Staines-Urías et al 2009) in the Gulf of California, and for Soledad Basin (Marchitto et al 2010, Deutsch et al 2014 off the west coast of the Baja California peninsula. Changes in marine productivity and water-column conditions have been linked to changes in solar activity during the late Holocene.…”

“…Moreover, the dinoflagellate Gymnodinium catenatum has inhabited the southern Gulf of California since 1483, and its relative and absolute abundance is positively/negatively modulated by El Niño/La Niña conditions (Flores-Trujillo et al 2009). Marchitto et al (2010) proposed that the variations in sea surface temperature are related to changes in solar activity.…”

“…Incluso, el dinoflagelado Gymnodinium catenatum ha estado presente en la región sur del golfo de California desde 1483, y su abundancia relativa y absoluta es modulada positiva/negativamente por condiciones de La Niña/El Niño (Flores-Trujillo et al 2009). Marchitto et al (2010) propusieron que la variabilidad de la temperatura del océano superficial está relacionada con la variabilidad de la actividad solar.…”

ABSTRACT. In this study we present new data of biogenic opal (BO), organic carbon (OC), and calcium carbonate (CaCO 3 ) in a highresolution record from the western coast of Baja California Sur, Mexico. The variability of marine biological productivity in this area is dominated by El Niño and La Niña events on different time scales. The BO and OC contents showed a decrease between AD 1100 and 1400. From AD 1400 to the present, BO and OC showed a significant increase, indicating permanent upwelling conditions. The CaCO 3 content showed an inverse correlation with OC, which suggests that the exported OC fluxes are a significant factor controlling CaCO 3 dissolution in the sediment. The increase in BO and OC was synchronic with a decline in the number of El Niño events (6 ± 4 every 100 years) over the last 600 years of the millennium.Key words: biogenic opal, organic carbon, El Niño, La Niña, upwelling. RESUMEN.En este trabajo se presentan nuevos datos de un registro de alta resolución de ópalo biogénico (OB), carbono orgánico (CO) y carbonato de calcio (CaCO 3 ) en la costa occidental de Baja California Sur, México. En esta región, la variabilidad de la productividad biológica marina es dominada por la intensidad de los eventos El Niño y La Niña en diversas escalas de tiempo. Los contenidos de OB y CO disminuyeron durante el periodo de AD 1100 a 1400. En el periodo de AD 1400 al presente, el OB y CO aumentaron significativamente, lo cual indica condiciones permanentes de surgencia. El contenido de CaCO 3 se correlacionó inversamente con el CO, y esto sugiere que los flujos de CO exportado son un factor significativo que controla la disolución de CaCO 3 en el sedimento. El incremento en el OB y CO fue sincrónico con la disminución en el número de eventos de El Niño (6 ± 4 cada 100 años) para los últimos 600 años del milenio.Palabras clave: ópalo biogénico, carbono orgánico, El Niño, La Niña, surgencia.
