    Abstract: Novel remote sensing methods and in situ observations reveal that intense dinoflagellate blooms occur frequently in Monterey Bay, California. Blooms can contain surface chlorophyll concentrations exceeding 500 μ g l −1 and occupy ∼5 to 80 km 2 . They occur primarily during August through November and can persist for 〉 1 month. Maximum bloom frequency and mean intensity are in a shallow ( 〈 25 m depth) area of the northeastern bay, in coincidence with the warmest surface water, low wind stress, and retentive circulation. These conditions favor dinoflagellates, which can vertically migrate to acquire nutrients in the thermocline and aggregate as "red tide" near the surface. Bloom incubation areas, also indicated in other coastal upwelling systems, may disproportionately influence regional bloom ecology.

    Bio‐optical properties in relation to an algal bloom caused by iron enrichment in the equatorial Pacific

    Abstract: In 1995 a massive bloom of phytoplankton composed primarily of diatoms was created by adding small quantities of iron to the surface waters of the equatorial Pacific. As part of this experiment, several bio‐optical parameters were measured using drifter instruments and shipboard measurements. The iron‐induced bloom resulted in dramatic changes in the bio‐optical properties of the study site, potentially resulting in light limitation of the phytoplankton at the peak of the bloom. The results also provide evidence for a shift in photosynthetic energy partitioning by the phytoplankton assemblage upon initial exposure to iron. It is unclear, however, whether the physiological changes associated with the bloom were purely a result of the iron addition, or were also influenced by changes in species composition. We hypothesize that iron‐induced changes in bio‐optical properties of equatorial Pacific waters could have far‐reaching effects on the global climate system.
