Depth profiles of water column dissolved methane, density and biomass of zooplankton (specifically, Chaoborus spp.), and measurements of methane extracted from Chaoborus spp. during two sampling campaigns in 2016

Depth profiles of water column dissolved methane (CH4), density and biomass of zooplankton (specifically, Chaoborus spp.), and measurements of methane extracted from Chaoborus spp. were collected from Beaverdam Reservoir, Vinton, VA, USA during two, 24-hr intensive sampling campaigns in fall 2016 (3-4 August and 16-17 September). The sampling campaign was designed to test the hypothesis that Chaoborus spp. can transport CH4 from the hypolimnion to the epilimnion of lakes and reservoirs as they migrate to the surface waters from the benthos at night in search of zooplankton prey, and results of the project are published in Carey et al. 2018. During both sampling events, depth profiles of water column methane and Chaoborus spp. density were collected at noon, dusk, midnight, 2 a.m., dawn, and noon the following day at a 1 m resolution. In addition, during the September sampling event depth profiles were collected 1 hour prior to and after dusk. Methane gas was extracted from live Chaoborus individuals at every depth and time point immediately after collection via gentle centrifugation in distilled water following McGinnis et al. 2017.

McMurdo Dry Valleys Lake Joyce near shore water column pressure and temperature

This data set includes the deployment of an anchored pressure transducer and suspended thermistor string in Lake Joyce, Pearse Valley, as part of a NASA Astrobiology: Exobiology and Evolutionary Biology project. Instruments were deployed prior to summer melt in December 2014 near a melt water stream and retrieved in December 2015. Thermistors were positioned in the fresh water lens under the ice cover, within the water column, and on the lake bottom. This dataset is funded through the NASA grant NNX13AI60G, with USAP event G-063. This project is not funded through the MCM LTER program. MCM LTER hosts this synergistic project.

MCR LTER: Coral Reef: Water Column: Particle sedimentation on the Forereef, Back Reef and Fringing Reef

This data package contains measurements of the sedimentation rate of particulate matter to the seafloor on the forereef, backreef and fringing reef of the north shore of Moorea, French Polynesia, during 2 to 4 seasons per year from August 2005 to January 2011. Measurements include estimates of the accumulation rate of particulate organic carbon (POC), particulate organic nitrogen (PON), and dry mass. Samples were collected with 2 different types of sediment traps. From August, 2005 to January 2008 samples were collected using plastic door matting placed in plastic trays 1 cm deep and 195.5 cm2 in area. From January, 2008 to January, 2011 samples were collected in plastic tubes 5.2 cm inside diameter and 17.5 cm high (21.26 cm2). During each sampling period 3 replicate traps were placed at random on the seafloor and retrieved approximately 24 hours later. See caveats to data interpretation in methods discussion.

MCR LTER: Coral Reef: Water Column: Zooplankton Composition and Abundance

This data package contains zooplankton abundance and taxonomic composition measured at 5 stations on the north shore of Moorea, French Polynesia: Forereef, Backreef, Fringing Reef, Cooks Bay, and Oceanic (5 km due north) from 2005 to 2010. Day time measurements over the reef were taken with a 30 cm, 200 μm mesh plankton net equipped with a slow speed General Oceanics Model 2030 flow meter. Nets were swum horizontally by a diver 1 m above the bottom at Forereef, Backreef and Fringing Reef sites. Daytime sampling at the Oceanic and Cooks Bay sites consisted of 0-50 m, 0-100 or 0-30 m vertical tows with a 30 cm, 200 μm mesh plankton net equipped with a standard General Oceanics Model 2030 flow meter. Nighttime sampling and some daytime sampling was done at the Forereef, Backreef and Fringing Reef sites using automated plankton pumps equipped with flow meters and 200 μm internal nets (described in Alldredge and King, 2009). These pumps sampled 75 cm above the bottom for 1 to 1.5 hours beginning at 11 pm local time. Nocturnal zooplankton abundance was sensitive to lunar phase. On some sampling dates pump samples were taken at the same depth in duplicate, or at several different depths simultaneously. The zooplankton time series was terminated when it became clear that the variability in zooplankton abundance over just 50 cm difference in depth over the reef was greater than the variability seasonally or even day to night (Alldredge and King, 2009).

Water column nitrate and ammonium concentrations, sediment oxygen, di-nitrogen (gas), nitrate, nitrite, ammonium, phosphate, and silicate flux from sealed, whole core incubations, Rowley River, Rowley, MA.

Tidal flats are critical components of coastal estuarine ecosystems characterized by high rates of benthic primary productivity and biogeochemical cycling. In order to investigate the impact of anthropogenic nutrient loading on tidal flat biogeochemistry we carried out a two-week fertilization experiment. Throughout the course of the study we conducted two light-dark, whole-core incubations and took measurements of three indicators of microphytobenthos activity in addition to quantifying the resident eastern mud snail (Ilyanassa obsoleta) population.

Six to eight sites in the Plum Island Sound estuary , the mainstem of the Parker River and Rowley River, in areas close to where other clam samples were being taken for other studies, were selected for monthly chlorophyll sampling to determine the concentration of phytoplankton at these sites.

Hach, OTT RLS measurements of water column depth at 15 minute intervals in the lower Plum Island Sound off the Ipswich Bay Yacht Club pier, Ipswich, MA, year 2015

Measurements of water column depth at 15 minute intervals in Plum Island Sound at the Ipswich Bay Yacht Club, for year 2015. OTT radar level sensor (RLS) installed September 20, 2011 out of the water under the concrete pad on the Ipswich Bay Yacht Club pier, Ipswich, MA. RLS was mounted so that continuous year round measurements can be conducted without the concern of ice flows damaging the sensor.
