Soil respiration and flux measurements from Watersheds 17 and 18,Coweeta Hydrologic Laboratory, Otto, NC.
In order to better understand soil respiration and Carbon Dioxide (CO2) fluxes, 90 closed container chambers were installed in 18 plots located at upper, mid, and lower-slope lcoations within Coweetas watersheds 17 and 18. For eighteen months, soil moisture, soil temperature, and CO2 measurements were taken through the collars of pipes located within each plots. These measurements were used to determine total flux and other statisitcal information in order to better understand these forest processes.
Soil respiration and temperature measurements at 5 GCE-LTER sampling sites from June 2003 to March 2005
Soil temperature and respiration were measured in tidal marshes at five GCE-LTER sampling sites. The sites represent estuaries of the Georgia coast (USA) that vary in delivery of freshwater and sediment. Replicate measurements were taken from several locations at each site (levee, marsh plain, and marsh dieback) on seven dates between June 2003 and March 2005 to evaluate the effects of freshwater input on soil respiration over time.

<p>This dataset includes skin conductance, ECG and respiration measurements for 20 healthy unmedicated participants (9 males and 11 females aged 23.68 +/- 2.94 years, gender information misprinted in Bach & Staib 2015) undergoing two 120-s periods of resting, attention, or mental arithmetic (adding numbers). Selection and order of the two periods is contained as group information. An event marker is recorded at the beginning and the end of each period.</p>
PsPM-SC2F: SCR, ECG, PPU and respiration measurements from a delay fear conditioning task with auditory CS, performed during MRI scanning
<p>This dataset includes skin conductance response (SCR), electrocardiogram (ECG), peripheral pulse unit (PPU) and respiration measurements for 18 healthy unmedicated participants (9 females and 9 males, age range: 18 - 34 years, mean age: 24.8 +/- 4.2) participating in a classical (Pavlovian) discriminant delay fear conditioning experiment with auditory CS, during MRI scanning. Also included are CS and US information, and ratings of CS after the experiment. Simple and complex CS were simple sine tone (4 s), and up or down frequency sweep sounds, respectively. US was a train of electric square pulses delivered with a constant current stimulator (Digitimer DS7A, Digitimer, Welwyn Garden City, UK) on participants' dominant forearm through a pin-cathode/ring-anode configuration. After the fear conditioning task, participants were first asked to report their subjective estimate of how likely they were to receive a shock after a given CS in the future, on a visual analogue scale of 0-100. Then they were asked to rate pairs of CS sounds with respect to which of the two stimuli they liked less.</p>

PsPM-PIT2 : PSR, SCR, ECG and respiration measurements from pavlovian to instrumental transfer tasks with visual CS and electrical US.
<p>This dataset consists of a three session experiment conducted with 38 healthy unmedicated participants (22 females and 16 males aged 24.8 +/- 3.6). The sessions were recorded on the same day with a self decided break. The first session is an instrumental conditioning, the second a classical (Pavlovian) discriminant delay fear conditioning and the third a Pavlovian-to-instrumental transfer task. For all three sessions this dataset contains electrocardyogramm (ECG), pupil size (PSR), respiration, and skin conductance (SCR) measurements. For the fear conditioning session CS+/CS- are visual stimuli of differently colored backgrounds. US is a train of electric square pulses delivered with a constant current stimulator on participants' dominant forearm through a pin-cathode/ring-anode configuration. SOA between the CS and US is 3.5 s. ITI is randomly determined on each trial to be an integer between 7 - 11 s. The instrumental stimuli are two images of differently colored vending machines cuing if the machine required a coin to dispense a chocolate (Approach) or if a coin should be averted from the machine, to prevent an already dispensed chocolate from being crushed by a newly dispensed soft drink can (Withdraw). The operant task asks subjects to repeatedly press the space key (Go) or withhold any key press (NoGo) to win chocolates. In the instrumental conditioning session, subjects play the game with grey background, and in the Pavlovian-to-instrumental transfer session they play the same operant game but with CS colored backgrounds instead of grey background.</p>

The sessions were recorded on the same day with a self decided break. The first session is an instrumental conditioning, the second a classical (Pavlovian) discriminant delay fear conditioning and the third a Pavlovian-to-instrumental transfer task. For all three sessions this dataset contains electrocardiogram (ECG), pupil size (PSR), respiration and skin conductance (SCR) measurements. For the fear conditioning session CS+/CS- are visual stimuli of differently colored backgrounds. US is a train of electric square pulses delivered with a constant current stimulator on participants' dominant forearm through a pin-cathode/ring-anode configuration. SOA between the CS and US is 3.0 s. ITI is 2.5 s. The instrumental stimuli are two images of differently colored vending machines cuing if the machine required a coin to dispense a chocolate (Approach) or if a coin should be averted from the machine, to prevent an already dispensed chocolate from being crushed by a newly dispensed soft drink can (Withdraw). The operant task asks subjects to repeatedly press the space key (Go) or withhold any key press (NoGo) to earn chocolates. In the instrumental conditioning session, subjects play the game with grey background, and in the Pavlovian-to-instrumental transfer session they play the same operant game but with CS colored backgrounds instead of grey background.</p>

Soil respiration measurements along climate and black spruce productivity gradients in interior Alaska
Soil respiration measurements were made using an infrared gas analyzer (IRGA; EGM-4 gas analyzer, PP Systems, Haverhill, MA) with a dynamic soil respiration chamber (SRC-2, PP Systems). Respiration collars (18) were randomly located on three 20 x 20 m sampling grids (separate from WSOC collection) at each site. The respiration collars (10.2 cm diameter schedule 40 polyvinyl chloride) were inserted to a depth of 2.5 cm at least 1 week prior to initial measurements and were left in place for the duration of the experiment. Care was taken to ensure that the collars remained at the same depth throughout the measurement period. All vascular plants were removed from the collars prior to measuring. Measurements were made approximately bi-weekly at each site, from May through September in 2004 (n = 5 or 6). A portable thermometer was used to measure soil temperature at 10 cm below the surface concurrently with soil respiration measured at each collar. Changes in collar-specific air volumes (caused by changes in microtopography and the presence of moss) were measured directly through use of the ideal gas law by injecting 25 cm-3 of 3500 mg m-3 CO2 into the soil respiration chamber and measuring the subsequent dilution of CO2 concentration with the IRGA. All flux values have been adjusted for these collar specific volumes.
Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR) Extended sites: winter ecosystem respiration chamber measurements using snow removal method. Oct-Nov 2009, Oct-Dec 2011, Oct-Nov; March-April 2012, Feb-May 2013.
The Carbon in Permafrost Experimental Heating Research (CiPEHR) project addresses the following questions: 1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C, that comprises the bulk of the soil C pool, influence ecosystem C loss?, and 3) How do winter and summer warming alone, and in combination, affect ecosystem C exchange? We are answering these questions using a combination of field and laboratory experiments to measure ecosystem carbon balance and radiocarbon isotope ratios at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. This dataset contains point measurements of winter ecosystem respiration fluxes using the snow removal method and the soil temperature, air temperature, and snow depth associated with each flux.
