2015/7/16
We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical ...

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...
Partitioning of primary production among giant kelp (Macrocystis pyrifera), understory macroalgae, and phytoplankton on a temperate reef

We experimentally investigated the response of phytoplankton and understory macroalgae to canopies of giant
kelp, Macrocystis pyrifera, by following changes in their biomass and net primary productio...

The nutrient climate on the inner shelf off southern California changed markedly across the 1976–1977 North
Pacific climate regime shift. With respect to giant kelp (Macrocystis pyrifera) canopies of...
Currents and turbulence within a kelp forest (Macrocystis pyrifera): Insights from a dynamically scaled laboratory model

2014/4/17
The effects of aMacrocystis pyriferaforest on currents and turbulence were investigated in a controlled laboratory setting using a dynamically matched 1/25-scale model. Two kelp configurations with su...
Experimental assessment of the effects of shade on an intertidal kelp: Do phytoplankton blooms inhibit growth of open-coast macroalgae?

Benthic primary producer abundance and satellite-derived chlorophyll concentrations are strongly negatively
correlated along the Oregon and Northern California coast, suggesting an antagonistic inter...
Internal Wave Attenuation by Coastal Kelp Stands
Internal Wave Coastal Kelp Stands low frequencies

Coastal kelp stands are a unique physical environment having high drag distributed throughout the water column. Temperature records from locations at increasing distances into the kelp show a damping ...
Physical pathways and utilization of nitrate supply to the giant kelp, Macrocystis pyrifera

2014/4/18
To determine the relative importance of different sources of nitrate to the annual nitrogen needs of the giant kelpMacrocystis pyrifera,we measured ambient nitrate concentrations at a kelp forest for ...
Modulation of wave forces on kelp canopies by alongshore currents
Modulation of wave forces on kelp canopies alongshore currents
font style='font-size:12px;'>
2014/5/20
The predominant view of the canopy-forming kelp’s mechanical response to water motion is that they sway passively under waves such that they are only rarely stretched out in flow, which reduces r...

2014/6/9
A study of water velocities near subtidal kelp fronds, relative to the motion of the kelp itself, is described. The dynamic model developed by Utter and Denny (1996) is used to develop a quantitative ...
