Dissolved organic carbon (DOC) concentrations in discrete water column samples collected from lakes in the McMurdo Dry Valleys, Antarctica (1993-2022, ongoing)
The McMurdo Long Term Ecological Research (LTER) project monitors patterns of organic material transport in perennial ice-capped lakes. This data set addresses this core area of research and quantifies dissolved organic carbon concentrations at specific depths in McMurdo Dry Valley lakes.
Ion concentrations in discrete water column samples collected from lakes in the McMurdo Dry Valleys, Antarctica (1991-2019, ongoing)
As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic aqueous geochemical sampling program has been undertaken. A series of terrestrial water samples have been collected and analyzed for major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids from fresh to hypersaline lake waters. This dataset shows concentrations of lithium, sodium, potassium, magnesium, calcium, chloride, bromide, silicon, fluoride, SO4, found in various depths of Taylor Valley lakes.
Microplankton counts from discrete water column samples using flow imaging microscopy (FlowCam) from Lakes Fryxell and Hoare, McMurdo Dry Valleys, Antarctica (2007-2011)
This data package consists of microplankton counts from discrete water column samples collected at various depths in Lake Fryxell and Lake Hoare in the McMurdo Dry Valleys region of Antarctica. Samples were collected and preserved during the austral summer-autumn transition in 2007-2008 and in addition to routine McMurdo Dry Valley Long Term Ecological Research (LTER) core limnological sampling in November and December of 2008, 2010, and 2011. Data were imaged using flow cytometry (FlowCam VS-IV) and classified with statistical image-based software (Visual Spreadsheet, v4.17.14). These data include haptorian ciliates, filamentous cyanobacteria, and coccoidal algae particle counts per milliliter that were automatically classified from user-built libraries and statistical filters based on the morphological characterizations of the plankton.
Haptorian ciliate measurements from discrete water column samples using flow imaging microscopy (FlowCam) from Lakes Fryxell and Hoare, McMurdo Dry Valleys, Antarctica (2007-2020)
This data package consists of particle diameter and biovolume data for haptorian ciliates classified from discrete water column samples collected at various depths in Lake Fryxell and Lake Hoare in the McMurdo Dry Valleys region of Antarctica. Samples were collected and preserved between November 2007 and January 2020 in Lake Fryxell and between November 2007 and March 2008 in Lake Hoare. Samples were collected and analyzed as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) core limnological sampling. Data were imaged using flow cytometry (FlowCam VS-IV) and imaged particles were classified with statistical image-based software (Visual Spreadsheet, v4.17.14). Diameter and biovolume was generated for each particle using FlowCam’s area-based diameter (ABD) algorithm.
MCR LTER: Coral Reef: Water Column nutrient data in lagoons of Moorea, French Polynesia
Nutrients are important for ecosystem structure and community dynamics. To quantify fine-scale patterns of variation in water column nutrients in tropical lagoon ecosystems, nitrite + nitrate, phosphate, and silicate were quantified from water column samples collected in lagoons around Moorea, French Polynesia during April-May starting in 2021 using flow injection with an automated ion analyzer. Over the first three years, water column nitrite + nitrate and silicate were higher in bays and fringing reef habitats, and phosphate was higher in bays.
MCR LTER: Coral Reef: Water Column: Offshore Water Profiles: CTD Transects
This dataset contains vertical water column profiles along transects heading offshore over the forereefs on the three sides of Moorea. These sides are designated north, southeast, and southwest. This process study intended to look for a hypothesized buoyant flow that would account for the counter-clockwise (CCW) circulation around the island. These transects were designed to look for cross-shore density gradients associated with the CCW flow. The SeaBird SBE19-Plus Profiler (CTD), outfitted with WetLabs FLNTURT-221 fluorometer, was cast at closely-spaced stations along transects oriented approximately normal to the three sides of the island. Standard CTD parameters (conductivity, temperature, and density) were used to calculate salinity, depth, and other physical quantities. No bottle samples were collected on these cruises.
MCR LTER: Coral Reef: Water Column: Bay Water Profiles: CTD Transects
This dataset contains vertical water column profiles along transects in Opunohu Bay and Cook’s Bay on the north side of Moorea. The SeaBird SBE19-Plus Profiler (CTD), outfitted with WetLabs FLNTURT-221 fluorometer, was cast at closely-spaced stations along transects down the length of the bays. Standard CTD parameters (conductivity, temperature, and density) were used to calculate salinity, depth, and other physical quantities. No bottle samples were collected on these cruises. Profiles in the bays were obtained when sea conditions offshore prohibited sampling over the forereef.
