Another critical point is that detrital feeders like sea cucumbers, brittle stars that wander around the bottom, I didn't see a living sea cucumber around on any of the wellhead dives.
Hence, as vegetation shifts from mosses and lichens to grasses and woody species, runoff is very likely to contain increasing concentrations of DOC and particulate detrital material.
Combined with greater DOC and nutrient loadings, higher water temperatures are likely to lead to a general increase in total stream productivity, although it is unclear whether temperature will have a significant direct effect on the processing rate of additional particulate detrital material.
Heinrich events occurred during times of decreasing sea surface temperatures in the form of brief, exceptionally large discharges of icebergs in the North Atlantic from the Laurentide and European Ice Sheets that left conspicuous layers of detrital material in deep-sea sediments.
When the ice begins to break up in spring, the seaweeds are torn from the rocks and enter into the detrital cycle.
These photosynthetic prokaryotes and analogous eukaryotic microalgae, which commenced growing in the Pool when it first formed about 4000 years BP, trap and bind detrital sediment and thereby create organo-sedimentary microbialites or microbial mats, which have mineralized to form stromatolites in Hamelin Pool.
Most of the primary productivity is routed through detrital pathways but herbivory can be important, particularly by muskrats and geese.
"The quartzite shows granoblastic and blastopsammitic texture, with grain sizes varying from coarse sand to very fine pebble and with minor microcrystals of sericite, fuchsite, andalusite and iron oxide, besides detrital tourmaline, rutile, and zircon." link
By September 2000, the meltwater channel had shifter southward and had eroded through 5 m of fluted moraine deposits exposing 2 additional rooted stumps and flushing an additional 40 detrital boles onto the outwash surface. gbalella
