The Isles of San Felix and San Nabor

Contribution to the Marine Algal Flora of San Felix Island, Desventuradas Archipelago, Chile!

Only 12 species of marine algae were known until now from the Desventuradas Archipelago. A recent collection added 10 species yielding a total of six Chlorophyta, nine Phaeophyta, and seven Rhodophyta. Only one species, Padina tristromatica Levring, is endemic. More than half of the representatives are in common with the flora of the Juan Fernandez Archipelago, but only five species are also fo...

Estimates of suspended sediment entering San Francisco Bay from the Sacramento and San Joaquin Delta, San Francisco Bay, California

This study demonstrates the use of suspended-sediment concentration (SSC) data collected at Mallard Island as a means of determining suspended-sediment load entering San Francisco Bay from the Sacramento and San Joaquin River watersheds. Optical backscatter (OBS) data were collected every 15 min during water years (WYs) 1995–2003 and converted to SSC. Daily fluvial advective sediment load was e...

Potential effects of global warming on the Sacramento/San Joaquin watershed and the San Francisco estuary

[1] California’s primary hydrologic system, the San Francisco estuary and its upstream watershed, is vulnerable to the regional hydrologic consequences of projected global climate change. Projected temperature anomalies from a global climate model are used to drive a combined model of watershed hydrology and estuarine dynamics. By 2090, a projected temperature increase of 2.1 C results in a los...
