Multiple Sources and Forms of Nitrogen Sustain Year-Round Kelp Growth on the Inner Continental Shelf of the Santa Barbara Channel
Nitrogen Sustain Year-Round Kelp Growth Santa Barbara Channel
2015/7/16
Forests of the giant kelp Macrocystis pyrifera found on coastal rocky reefs lack the large reservoirs for nutrient storage found in many terrestrial environments. Supporting their high year-round grow...
Characteristics and sources of chromophoric dissolved organic matter in lakes of the Yungui Plateau, China, differing in trophic state and altitude
Characteristics sources of chromophoric dissolved
2014/4/17
The high-mountain lakes on the Yungui Plateau in China are exposed to high-intensity ultraviolet radiation, and
contain low concentrations of chromophoric dissolved organic matter (CDOM). We determin...
Supply of gastropod larvae to hydrothermal vents reflects transport from local larval sources
Supply of gastropod larvae hydrothermal vents
2014/4/21
Variation in larval supply to disjunct marine populations can provide insight into larval transport and delivery
mechanisms, especially when compared with observations of physical transport. Daily va...
Sources and transport of terrestrial organic matter in Vancouver Island fjords and the Vancouver–Washington Margin: A multiproxy approach usingd13Corg, lignin phenols, and the ether lipid BIT index
terrestrial organic matter Vancouver Island fjords the Vancouver–Washington Margin multi proxy approach d13 Corg lignin phenols ether lipid BIT index
2014/4/21
The Branched and Isoprenoid Tetraether (BIT) index (a ratio of marine and terrestrial glycerol dialkyl glycerol tetraether [GDGT] membrane lipids) was recently introduced as a proxy for the fraction o...
Hurricane signals in salt marsh sediments: Inorganic sources and soil volume
Hurricane signals salt marsh sediments Inorganic sources soil volume
2014/4/22
The inorganic content of 51 dated sediment cores from Mississippi River deltaic plain salt marsh wetlands peaks with the landfall of hurricanes. Variations in the inorganic sediment content demonstrat...
Nitrogen sources and cycling in the San Francisco Bay Estuary: A nitrate dual isotopic composition approach
Nitrogen sources cycling San Francisco Bay Estuary nitrate dual isotopic composition
2014/5/4
We used the dual isotopic composition of nitrate (δ15N and δ18O) within the estuarine system of San Francisco (SF) Bay, California, to explore the utility of this approach for tracing sources and cycl...

Distribution and sources of cyclic pheophorbides in the marine environment
Distribution sources cyclic pheophorbide marine environment
2014/6/17
The labile chlorophyll a (Chl a1 ) degradation product, 132 ,17 3 -cyclopheophorbide a enol (CPP516), was only recently found in marine sediments, where it can contribute a significant fraction to sol...
