• 301. [Article] Chlorophyll natural fluorescence response to upwelling events in the Southern Ocean

  Citation × Citation Citation Abstract Copy Title: Chlorophyll natural fluorescence response to upwelling events in the Southern Ocean Author: Abbott, Mark R., Karl, David M., Letelier, Ricardo M. Variability of solar-induced (natural) fluorescence and chlorophyll were measured on scales of hours to weeks in the upper layer of a cyclonic eddy located south of the Antarctic Polar Front using a free-floating drifter. The fluorescence signal was analyzed both in terms of chlorophyll concentration and as an indicator of energy distribution in the photosynthetic apparatus. Long-term trends in fluorescence parallel changes in chlorophyll concentration. Considering a significant positive correlation between fluorescence and the relative depth of the eddy upper layer we hypothesize that the observed short-term variations in natural fluorescence are a physiological response of phytoplankton to changes in the supply of limiting nutrients. This interpretation is consistent with the Southern Ocean iron limitation hypothesis.

• 302. [Article] Changes in wind-driven upwelling during the last three centuries: Interocean teleconnections

  Analysis of sediments from two wind-driven upwelling systems, Guaymas and Cariaco basins, using the alkenonebased U_37^(K^' ) paleothermometer yielded high-resolution records of sea surface temperatures ...

  Citation × Citation Citation Abstract Copy Title: Changes in wind-driven upwelling during the last three centuries: Interocean teleconnections Author: Müller-Karger, Frank E., Goni, Miguel A., Thunell, Robert C., Woodwort, Mark P. Analysis of sediments from two wind-driven upwelling systems, Guaymas and Cariaco basins, using the alkenonebased U_37^(K^' ) paleothermometer yielded high-resolution records of sea surface temperatures (SST) from 1700 to 2000 AD. The trends in the U K'/37 index reveal steady SST increases of 1 to 2°C at both sites since the end of the Little Ice Age. Higher-frequency changes in SST indicate a decoupling in the relative intensity of wind-driven upwelling at the two sites. Periods of enhanced upwelling in Guaymas correspond to periods of decreased upwelling in Cariaco (and vice versa). We propose that these contrasts reflect regional differences in the upwelling response of upwelling to changes in the positioning of the Inter-Tropical Convergence Zone (ITCZ) and the Subtropical High (SH) under current climate conditions.

  Citation × Citation Citation Abstract Copy Title: Enhancement of cloud cover and suppression of nocturnal drizzle in stratocumulus polluted by haze Author: Coakley, James A., Stevens, D. E., Ackerman, A. S., Toon, O. B. Recent satellite observations indicate a significant decrease of cloud water in ship tracks, in contrast to an ensemble of in situ ship-track measurements showing no average change in cloud water relative to the surrounding clouds, and contrary to the expectation of cloud water increasing in polluted clouds. We find through large-eddy simulations of stratocumulus that the trend in the satellite data is likely an artifact of sampling only overcast clouds. The simulations instead show cloud cover increasing with droplet concentrations. The simulations also show that increases in cloud water from suppressing drizzle by increasing droplet concentrations are favored at night or at extremely low droplet concentrations.

Forest Research Laboratory, Rasker, Ray, Johnson, Rebecca L., 1955- Trends in fee hunting in Oregon are examined, with particular emphasis on waterfowl in the western part of the state. Farmers with potential or existing waterfowl habitat in western Oregon were surveyed about their views on managing their lands for waterfowl. As incentives to such practices, they listed the financial returns from leasing access to hunting, aesthetic appreciation of waterfowl, and personal enjoyment from waterfowl hunting. As deterrents, they listed negative attitudes toward hunters and concerns over lawsuits by hunters. They also identified damage to crops by waterfowl as a source of friction between wildlife agencies and landowners.
