Saccharina compla(nada?) Species Determining the validity of S. complanata as a distinct species
(2023)The kelp species Saccharina complanata (order Laminariales, family Laminariaceae) originally described as Saccharina latissima f. complanata, is a poorly understood species, often overlooked in studies involving other ... -
Salinity Fluctuation’s Effect on Dendraster excentricus Developmental Defects
(Friday Harbor Laboratories, 2013-08)Preliminary studies suggest that salinity concentrations affect the developmental defect known as exogastrulation in the sand dollar Dendraster excentricus. Gastrulation is a very important morphological change as the ... -
Salinity stress cross-tolerance of Ostrea lurida after exposure to acidified ocean conditions in a simulated freshet discharge
(2023)Ocean acidification is widely regarded as a serious danger to marine organisms, especially calcifying invertebrates, but how this might interact with other abiotic stressors in realistic environmental events is less well ... -
San Juan Channel Seabird Abundance Patterns of Fall
(Friday Harbor Laboratories, 2013-12)Seabirds are an important component of many marine ecosystems, but are in decline in many parts of the world. While some studies have shown that Salish Sea seabirds are declining, PEF has found no evidence of this decline. ... -
Sargassum Muticum effects on Costaria Costata and Benthic Assemblages of Marine Primary Producers
(2021)The introduced species Sargassum muticum has been part of Salish Sea ecosystems since the 1940s. It has become extremely common in both Europe and North America, growing in the shallow subtidal. I combined a series of ... -
Satellite based productivity models across the Kuroshio extension
(2013-06)[author abstract] As anthropogenic perturbations to the Earth’s climate have continued to become more severe, it has become increasingly necessary to understand the processes that control atmospheric CO2. One such process ... -
Satellite Remote Sensing of Chlorophyll: Significance of PAR & Spatial Scale
(2012-06)[Author's abstract] Satellite remote sensing is used worldwide in many different sectors of science. The advent of remote sensing allows a global database of daily information. The National Aeronautics and Space Administration’s ... -
Sawing Efficiency in Elasmobranch Teeth
(Friday Harbor Laboratories, 2014-07)Previous research has shown little effect of tooth shape on puncturing ability (Whitenack & Motta, 2010), and though the concept of shark teeth as a saw blade has been explored, it has not been manifested beyond mathematical ... -

Scaling of Burial Mechanics in Parophrys vetulus, the English Sole
(Friday Harbor Laboratories, 2015-09)Flatfishes (Pleuronectiformes) rapidly bury themselves under sediments using body undulations and fin movements. During burial, a fish must fluidize a volume of the substrate to displace it into the water column and ... -
Scaling response of a canyon-incised shelf break
(2012-06)[Author's Abstract] The continental shelf break is a global, large-scale geologic structure which separates continents from the deep sea. Along the shelf break many finer-scale features can be recognized, such as canyons ... -
Scavenging Rates and Community Composition at Different Habitats along a Shallow Water Depth Gradient
(Friday Harbor Laboratories, 2014-08)As fisheries grow and the amount of bycatch being thrown back into the oceans rises, studies on the effects of interferences in natural food chain processes that occur throughout the ocean become increasingly important. ... -
Scavenging Rates and Community Composition at Different Habitats along a Shallow Water Depth Gradient2
(Friday Harbor Laboratories, 2014-08)As fisheries grow and the amount of bycatch being thrown back into the oceans rises, studies on the effects of interferences in natural food chain processes that occur throughout the ocean become increasingly important. ... -
Sea Star Acrobatics: Testing the Righting Response of Eight Different Asteroid Species on Two Different Substrata
(Friday Harbor Laboratories, 2012-07)Sea stars typically live with their oral side facing the substratum, and the ability to right themselves when turned over is important response to avoid desiccation and predation. The righting time of 8 species of sea ... -
Seabirds and Tides at Fine Temporal Scales
(Friday Harbor Laboratories, 2013-12)Intricate tidal dynamics are the main drivers of ecosystem processes in coastal estuaries. Previous Pelagic Ecosystem Function studies have explored the relationship between tidal activity and seabird abundance in the San ... -
Seafloor terrain and sediment characterization at Molokaʻi, Lōʻihi, and Cross Seamount via seafloor mapping
(2011-03)Research conducted between 27 Dec. 2010–4 Jan 2011 in Hawaii, at Molokai, Loihi, and Cross Seamount, combined seafloor mapping with sediment analysis to provide a comparison of different sediments over different terrain ... -
The Search for Putative Mesoderm and Muscle Specific Genes in Pleurobrachia bachei
(Friday Harbor Laboratories, 2012-06)There has been a long debate in the scientific community over the oldest surviving metazoan lineage. Traditionally it has been taught that Porifera, the sponges, occupy that nitche possessing a diploblastic body plan ... -

Searching for Slit and Robo in the Ascidians, Boltenia villosa and Molgula oculata
(Friday Harbor Labs, 2011-09)The axonal guidance molecules slit and robo are known to interact producing a repulsive signal to the growing processes of nerve cells during development. These signals contribute to the proper ‘wiring’ of nervous systems. ... -
Seasonal and tidal effects on water density gradients in the San Juan Channel
(Friday Harbor Labs, 2011-12)The San Juan Channel is one passageway linking the Strait of Georgia and the Strait of Juan de Fuca. Thus, the physical oceanography of this region is complex and has both estuarine and oceanic influences. We sampled a ...
