... an example of the interaction of kelp (Order Laminariales) and coarse sediment transport in the coastal zone, where it is possible to directly quantify and test its effect. Kelp is ubiquitous along rocky coastlines and the impact on ecosystems has been well studied. We develop a physical model to explore...

...). There is a concomitant decrease in organic carbon with depth, and it appears that a part of this carbon is responsible for the generation of methane under reducing conditions below 2 m or so. The source of the organic carbon could be kelp, produced in abundance in the Bay, which has a very high primary productivity...

...K. O. EMERY; R. H. TSCHUDY Abstract In addition to being rafted by ice and by drifting logs, pebbles may be carried by kelp holdfasts to be dropped into deep-water sediments after the floating kelp has decayed or been eaten. Many shallow-water organisms similarly may be deposited in foreign...

...-exposed margins of the coastal plat-forms, kelp forests provide habitats for numerous carbonate-secreting organisms such as barnacles, echinoids, and bivalves. Kelp with attached calcareous organisms is involved in many redistributional processes such as rafting and "phylloid drift". Reef growth...

The common giant kelp which forms the extensive kelp beds along this coast ( Macrocystis pyrifera Linnaeus) is commonly considered to be a good criterion for the presence of bedrock outcrops. This is now known to be partly...

... on the midshelf seafloor of the islands provide good habitats for demersal rockfish ( Sebastes spp.), and rock outcrops in the nearshore areas provide hold-fasts for kelp, which can provide habitat for larval and young-of-the-year rockfish. Although true habitat is not well known in the areas studied...
