Slicks as Indicators for Marine Processes
Slicks Indicators Marine Processes
font style='font-size:12px;'>
2015/7/16
Monomolecular surface films ("sea slicks") are well known to dampen small-scale waves at the water surface, thereby influencing transport processes at the air-sea interface. Because of their strong wa...
Sulfur stable isotope indicators of residency in estuarine fish
Sulfur stable isotope indicators of residency estuarine fish
font style='font-size:12px;'>
2014/4/4
Estuarine fish may remain as residents in areas with favorable conditions for feeding and refuge, but become mobile and transient where conditions are less favorable. We developed a new approach invol...
Absorption spectral slopes and slope ratios as indicators of molecular weight, source, and photobleaching of chromophoric dissolved organic matter
Absorption spectral slopes slope ratios indicators of molecular weight source photo bleaching chromo phoric dissolved organic matter
font style='font-size:12px;'>
2014/4/21
A new approach for parameterizing dissolved organic matter (DOM) ultraviolet-visible absorption spectra is presented. Two distinct spectral slope regions (275–295 nm and 350–400 nm) within log-transfo...
Energy reserves and metabolism as indicators of coral recovery from bleaching
Energy reserves coral recovery
font style='font-size:12px;'>
2014/4/22
With reduced zooxanthellae, chlorophyll a (Chl a), or both, concentrations, bleached corals rely on some
combination of energy reserves (i.e., lipid, carbohydrate, protein) and heterotrophy to surviv...
Iron limitation across chlorophyll gradients in the southern Drake Passage: Phytoplankton responses to iron addition and photosynthetic indicators of iron stress
Iron limitation chlorophyll gradients in the southern Drake Passage Phytoplankton responses iron addition photosynthetic
font style='font-size:12px;'>
2014/4/21
Processes influencing phytoplankton bloom development in the southern Drake Passage were studied using shipboard iron-enrichment incubations conducted across a surface chlorophyll gradient near the An...
Investigating the use of macrophyte stable C and N isotopic ratios as indicators of wetland eutrophication: Patterns in the P-affected Everglades
macrophyte stable C N isotopic ratios wetland eutrophication Patterns in the P-affected Everglades
font style='font-size:12px;'>
2014/5/5
We investigated the use of stable C and N isotopic ratios as indicators of shifts in nutrient limitation of aquatic macrophytes in native Typha (Typha domingensis Pers.) and Cladium (Cladium jamaicens...
Paleo-indicators and water quality change in the Charlotte Harbor estuary (Florida)
Paleo-indicators water quality
font style='font-size:12px;'>
2014/4/30
We reconstructed water quality changes for 1800 to 2000 in Charlotte Harbor (Florida), a shallow subtropical
estuary, by using a suite of biological and geochemical proxies in dated sediments collect...
Radium isotopes in Cayuga Lake, New York: Indicators of inflow and mixing processes
Radioisotopes Cayuga Lake New York Indicators inflow mixing processes
font style='font-size:12px;'>
2014/5/8
Naturally occurring radium isotopes (223Ra, 224Ra, 226Ra, and 228Ra) were measured in lake and tributary water of Cayuga Lake, New York, during the course of a vernal inflow event in the spring of 200...
