| log in | [EN584 Bulk PA FlaPS Rates] - Polysaccharide hydrolysis rates from bulk water and 3 µm retained fraction (particle-associated) incubations in the Northwest Atlantic aboard the R/V Endeavor cruise EN584 from Jun to Jul 2016 (Latitudinal and depth-related contrasts in enzymatic capabilities of pelagic microbial communities: Predictable patterns in the ocean?) | The potential of the seawater microbial community to hydrolyze six high-molecular-weight polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan) was investigated at various sites and depths of the Northwest Atlantic. Nearshore waters close to Cape Hatteras/Cape Lookout, and a transect along ~36° N out to ~58° W were collected during the summer of 2016, aboard the R/V Endeavor cruise EN584. Hydrolysis of high molecular weight substrates to lower molecular weight hydrolysis products was measured using gel permeation chromatography with fluorescence detection, after the method of Arnosti (1996, 2003). This dataset includes polysaccharide hydrolysis rates to measure microbial enzyme activities from bulk water and 3 µm retained fraction (particle-associated) incubations.\n\ncdm_data_type = Other\nVARIABLES:\nDeployment (unitless)\nstn (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nISO_DateTime_Local (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\ncast_number (unitless)\ndepth_sequence (unitless)\ndepth (Depth_actual, m)\nsample_type (unitless)\namended_unamended (unitless)\nsubstrate (unitless)\ntimepoint (unitless)\ntime_elapsed_hr (hours)\nrep1_rate (nM*hr-1)\nrep2_rate (nM*hr-1)\nrep3_rate (nM*hr-1)\naverage (nM*hr-1)\nstd_dev (nM*hr-1)\n | BCO-DMO | bcodmo_dataset_986681_v1 | ||||||||||||

The existence of a size-reactivity continuum of DOM - observations and measurements showing that high molecular weight (HMW) DOM tends to be younger and more reactive than lower MW DOM - has been demonstrated in laboratory and field investigations in different parts of the ocean.
