Oceanic Flux Program
(Adapted from the NSF Project Summary)
Since 1978, the Oceanic Flux Program (OFP), originally founded and managed by at the Woods Hole Oceanographic Institution and now managed by the Bermuda Institute of Ocean Science (BIOS), has continuously measured particle fluxes in the deep Sargasso Sea. The 35+ year OFP time-series is, by far, the longest of its kind and unique in its focus on the deep ocean. OFP has produced a unique, albeit "edited", record of temporal variability in the "biological pump", a term loosely applied here to material transfer from the surface to the deep ocean. The OFP provided the first direct evidence for seasonality in the deep ocean and the tight coupling between deep fluxes and upper ocean processes. It has provided clear evidence of the intensity of biological reprocessing of flux and scavenging of suspended material in mesopelagic waters. The record has documented interannual and longer variations in deep fluxes and shorter term fluctuations driven by the interactions between mesoscale physical variability, meteorological forcing and ecosystem responses.

Time Series Particle Flux Measurements in the Sargasso Sea
<p><em>NSF Award Abstract:</em><br />
This award continues, for another three years, the Ocean Flux Program (OFP) that has been in continuous operation near Bermuda since 1978. The OFP time-series of particle fluxes in the deep Sargasso Sea has produced a unique record of the "biological pump," a term used to describe the sinking of biological material from the surface to the deep ocean. The OFP provided the first direct evidence for seasonal changes in the deep ocean and tight links between deep ocean and upper ocean processes. The OFP provides clear evidence for the intensity of biological activity throughout the ocean's interior and the roles of key processes in biogeochemical and elemental cycling. The time-series is becoming long enough to study flux variability in terms of ocean basin-scale forcing, such as the North Atlantic Oscillation. The OFP sample archives are an unparalleled resource for study of temporal trends and the biogeochemical consequences of changing ocean chemistry. Education provided by the OFP broadens the experiences and science directions of many students (high school to PhD levels) and early investigators at critical career junctures.</p>
<p>The OFP time-series is the longest of its kind and unique in its focus on the deep ocean. As the record lengthens, investigators are better able to put into perspective the observed flux patterns in terms of the interplay between climate and ocean functioning. Colocation of complementary time-series -- Hydrostation S, the Bermuda Atlantic Time-Series (BATS), the Bermuda Testbed Mooring (BTM, 1994-2007), the Tudor Hill atmospheric tower and other sampling conducted near the Bermuda Time-Series Site -- and continuing advances in instrumentation on the OFP mooring present unparalleled opportunities to study coupling among ocean physics, biology and chemistry and material fluxes, and flux linkages with atmospheric and climatic forcing. As ever more sophisticated analytical tools are used to probe the recovered flux materials, new data continue to reveal novel information about ocean processes.</p>

PI Supplied Instrument Name: PI Supplied Instrument Description:The SCIFF mooring consisted of a single 1.54m2 conical sediment trap located at 3200m water depth (total water depth 4200m). The 1.54m2 trap had only a single collection cup under the trap funnel, and the mooring was recovered every two months to change the sample. Instrument Name: Sediment Trap Instrument Short Name:Sediment Trap Instrument Description: Sediment traps are specially designed containers deployed in the water column for periods of time to collect particles from the water column falling toward the sea floor. In general a sediment trap has a jar at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. This designation is used when the specific type of sediment trap was not specified by the contributing investigator. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/33/

Between 1995-2004, organic carbon and nitrogen were determined directly on pre-acidified samples using either a Carlo Erba or Perkin Elmer 240 CHN instrument. Instrument Name: CHN Elemental Analyzer Instrument Short Name:CHN_EA Instrument Description: A CHN Elemental Analyzer is used for the determination of carbon, hydrogen, and nitrogen content in organic and other types of materials, including solids, liquids, volatile, and viscous samples.

Zeiss Stemi SV-11 stereomicroscope
Zeiss Stemi SV-11 stereomicroscope
PI Supplied Instrument Name: Zeiss Stemi SV-11 stereomicroscope PI Supplied Instrument Description:The >1000um fraction is then rinsed into a pre-weighed Teflon petri dish, swimmers removed under a stereomicroscope (Zeiss Stemi SV-11), and photographed.
The 500-1000um and 125-500um fractions are rinsed into preweighed glass petri dishes using deionized water, quantitatively photographed using a Zeiss Stemi SV-11 stereomicroscope in conjunction with an Olympus Q-Color 5 (5.0 MP) camera as described in Shatova et al. (2012, J. Plankton Res. 34, 905-921). Instrument Name: Microscope - Optical Instrument Short Name: Instrument Description: Instruments that generate enlarged images of samples using the phenomena of reflection and absorption of visible light. Includes conventional and inverted instruments. Also called a "light microscope". Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/LAB05/
Parflux conical sediment traps
Parflux conical sediment traps
PI Supplied Instrument Name: Parflux conical sediment traps PI Supplied Instrument Description:In 1989, the 1.54m2 traps were replaced by the newly introduced 0.5m2 Parflux conical sediment traps (McLane Labs, Falmouth MA) having a rotating carousel to allow for multiple samples to be collected during a single deployment. The introduction of the Parflux trap (PARFLUX Mark 7G-13, Mark 7G-21 and currently Mark 78G-21) enabled the sampling period to be reduced from a nominal two month duration to a nominal two week duration. Instrument Name: McLane PARFLUX Mark 8 Sediment Trap Instrument Short Name:McLane PARFLUX Mark 8 Instrument Description: The Mark 8 Sediment Trap is a time-series instrument that autonomously collects the flux of settling particles on an operator-defined schedule. The wide top funnel accumulates particulate specimens into individual sample bottles. The cone interior is natural polyethylene. Deploys from a stand-alone mooring or a large high-tension vertical array.
