Between 15 September 2021 and 26 September 2023, we also deployed a s::can spectro::lyser V3 UV-Vis spectrophotometer (Messtechnik GmbH, Vienna, Austria) to measure light absorbance at wavelengths from 190 to 750 nm at 2.5 nm intervals every 15 minutes. These absorbance spectra were turbidity-compensated using a s::can proprietary algorithm.  Due to the complexity of the absorbance spectra time series generated by the submersible UV-Vis spectrophotometer,  we used a simplified data quality assurance method to filter out erroneous absorbance spectra. We used error codes recorded on the instrument, field notes, and water-level and turbidity data from the watershed outlet to help remove all spectra during periods of instrument malfunction, burial, and desiccation. We further filtered the absorbance data time series by first selecting three wavelengths (200 nm, 255 nm, 400 nm) to be representative of the entire UV-VIS absorbance spectra. We removed entire recorded spectra when 1) absorbance values at a given time point were negative at 200 or 255 nm and 2) when absorbance values at a given time point exceeded three standard deviations of the rolling mean absorbance values at 200, 255, or 400 nm.\", \"subject\": [\"Water Quality\", \"absorbance\", \"Piedmont\", \"AIMS\", \"s::can\", \"Talladega\"], \"created\": \"2025-07-29T19:17:24\", \"modified\": \"2026-04-06T03:41:24\", \"short_id\": \"cea7ec0e055f49ef9f55fc61caffc52a\", \"geo\": {\"short_id\": \"cea7ec0e055f49ef9f55fc61caffc52a\", \"title\": \"AIMS Talladega Absorbance Spectral Fingerprint at Watershed Outlet (AIMS_SE_TAL_SCAN)\", \"coverage_type\": \"point\", \"north\": 33.7719, \"east\": -85.5954}}, {\"title\": \"AIMS Shambley Creek Continuous Water Quality at Watershed Outlet Data (AIMS_SE_WHR_EXOS)\", \"link\": \"/resource/a7bdb79e06684db2886a257ec614018a/\", \"availability\": [\"public\"], \"availabilityurl\": \"https://storage.googleapis.com/hydroshare-prod-static-media/static/img/public.png\", \"type\": \"Resource\", \"author\": \"Plont, Stephen\", \"authors\": [\"Plont, Stephen\", \"Wolford, Michelle\", \"Peterson, Delaney\", \"Speir, Shannon\", \"Smith, Chelsea\", \"Zarek, Kaci\"], \"contributor\": null, \"author_link\": \"/user/26291/\", \"owner\": \"Plont, Stephen\", \"abstract\": \"This resource contains high-frequency EXOS water quality sensor data collected at the outlet of the Talladega study watershed, including conductivity, dissolved oxygen, turbidity, fluorescent dissolved organic matter concentrations, and temperature.

Global carbon emission estimates are limited by sparse and unevenly distributed carbon flux observations, particularly in the tropics. We evaluated hydrological and metabolic controls on carbon export variability from a large peatland in a tropical ecosystem typical of the Northern Andes mountains. We recorded dissolved CO2 (pCO2), dissolved oxygen (DO), and discharge continuously at 15-minute intervals 5 m downstream of a peatland outlet (Station 1) and at 3 additional locations downstream (Stations 2, 3 and 4) from July 2019 until Jan 2020 and from June 2021 until March 2023. Continuous measurements of DO and discharge were also measured 2 km away in a stream draining an adjoining catchment (Station 5). Discrete measurements of dissolved organic carbon (DOC) and dissolved methane (pCH4) were collected June-July of 2021 and 2022. Stream discharge was a primary control on pCO2 and DOC in the stream network at both seasonal and event scales. DOC concentration increased with discharge and while pCO2 decreased during higher flows, CO2 loading increased. Pronounced seasonal changes were observed with lowest pCO2 recorded at the peatland outlet in wet months (June-August: 5,845\\u00b12,325 ppm, mean\\u00b1standard deviation), and the highest in dry months (Nov-Feb, 16,677\\u00b13,685). Anoxic or hypoxic conditions persisted for over half of our study and measurements of pCH4 at the peatland outlet were very high (982\\u00b1797 ppm), underscoring the importance of anaerobic activity in this system. Aerobic processes also influenced pCO2 dynamics. Aquatic metabolism at Station 5 (29 July\\u201319 Oct 2021) was net heterotrophic, with ER exceeding GPP and net pCO2 production (mean ER: -6.5 g O2 m-2 d-1, GPP: 0.44 g O m-2 d-1).

We generally used a surber sampler, though if water was too deep, a D-net was used to scrub a similar area (0.09 m2) or when channels became too constrained a mini surber was employed (0.02 m2). We compiled all six samples into a composite sample, removed debris and leaf matter via manual inspection of material and elutriation, and sieved the remaining sample through a 500 \\u00b5m sieve. We then preserved the sample in 95% ethanol and returned it to the lab. In the lab, ethanol was refreshed before we froze the sample in a -20 \\u00baC freezer. We shipped samples to a commercial lab (Jonah Ventures, Boulder, CO) for metabarcoding analysis of the invertebrate community. Briefly, Jonah Ventures homogenized community samples with a hand immersion blender and extracted DNA with a DNeasy Powersoil Kit following the manufacturer\\u2019s protocol. They then amplified samples using two primers from the CO1 gene (CO1 F230 fragment Hajibabaei et al. 2012; CO1 BE fragment Folmer et al. 1994, Gibson et al. 2015). They conducted PCRs with initial denaturation at 95 \\u00baC for 5 min, followed by 40 cycles of 40s at 95 \\u00baC, 1 min at 46 \\u00baC, 30s at 72 \\u00baC and a final elongation at 72 \\u00baC for 10 min. They then cleaned samples using Exo1/SAP, and pooled, normalized and indexed. Samples were sent for sequencing at the CU Boulder BioFrontiers Sequencing Center where the Center used the v2 500-cycle kit with appropriate quality control measures. Jonah Ventures then demuliplexed sequenced samples using phigs v2.1.0 followed by removal of gene primers and merging read pairs. Read pairs were then clustered using unoise3 denoising algorithm in vsearch and with sequences with less than 8 reads discarded. Taxonomy was assigned using a custom best-hits algorithm with reference to NCBI Gen Bank to each Exact Sequence Variant (ESV) (See linked Jonah Venture documents for full methods).

The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3\\u00b0C and 25.3\\u00b0C respectively, and mean annual precipitation of 1,400 mm/yr. \\n\\nOn six different occasions from March 29, 2022 to January 29, 2024, we collected dissolved gas (MIMS) samples seasonally across 7 sampling locations (approach 2). On one separate occasion during June 2022, we collected MIMS samples from 49 sampling locations (approach 3) within the same Talladega research watershed. For the approach 3 sampling campaign, the sites were selected to balance multiple competing priorities: (i) strategically targeting existing monitoring infrastructure with long-term data; (ii) including sites near several known springs and tributary junctions; and (iii) including a range of drainage area and topographic wetness index (TWI) values, both of which have been correlated with flow permanence. Briefly, the sites selected based on drainage area and TWI were chosen by binning drainage area into 10 bins and then binning TWI into quintiles within each drainage area bin. We then randomly selected a point in each bin after accounting for points selected based on existing infrastructure, springs, and tributaries, as well as enforcing a minimum spacing of 100 m between locations. We then made minor adjustments to points to account for field conditions, for instance adjusting locations with respect to a road crossing. \\n\\nIncluded in the Content section is the sampling datasheet that was used during field collection, as well as one compiled excel file containing approach 2 and 3 MIMS TAL data. Within the compiled excel file, the 'Working Files' tab contains the processed MIMS data before taking averages of all the replicates. The 'Final Data' tab has the data that should be used for analyses with the averages of all 3 replicates and standard deviations (sd) in uM units. Also, there are columns regarding whether the sample was from approach 2 or 3.

Samples were filtered in the field with a 0.45um PES filter and acidified to 2% nitric acid for preservation until analysis. Immediately prior to analysis, samples were filtered with a 0.2um PES filter. Aqueous concentrations of cations were determined using coupled plasma-atomic emission spectrometry (ICP-AES) (Horiba Ultima 2, Horiba Jobin Yvon) fitted with an AS 500 autosampler. The instrument has a glass concentric nebulizer equipped with a cyclonic chamber. The generator power is 1000 W. The plasma and auxiliary gas flow rate are 12 L/min and 0 L/min. The sheath gas flow rate and nebulizer are 0.2 and 0.8 L/min. Argon pressure is 80 psi. Multi-elemental standards are prepared in 2% nitric acid as well.\\n\\nIntermediate tab has data from all triplicates; final data shows only triplicate average, st dev, and RSD (relative st dev). RSD (relative standard deviation is included in intermediate tab; red color indicates values above 10%). We recommend that users use what is presented in the final data tab, as not every replicate has been accounted for and the data has been cleaned.\\n\\nLow standard for each analyte (below): our lab uses this as the conservative detection limit/LOD. Na - 0.5 ppm / Ca - 0.5 ppm / B - 0.02 ppm / Mg - 0.5 ppm / Si - 0.5 ppm / K - 0.2 ppm / Sr - 0.05 ppm. Note: Boron (B) is almost always below our lowest standard.

The watershed drains a non-perennial unnamed tributary of Pendergrass Creek, and contains 0.92 km^2 of mixed coniferous and deciduous forest in the Piedmont Upland physiographic section. Located near Anniston, AL, the watershed spans an elevation range from 345 to 456 m above sea level and is a tributary to the Coosa River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3\\u00b0C and 25.3\\u00b0C respectively, and mean annual precipitation of 1,400 mm/yr. These samples were collected in support of the core sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. Between 7 October 2021 and 30 January 2023, grab samples for Total Suspended Solids (TSS, mg/L) and seston Ash Free Dry Mass (AFDM, mg/L) were collected at the watershed outlet (TLM01) every 3 weeks during routine sensor maintenance (AIMS Approach 1), seasonally at seven distributed, long term monitoring sites (AIMS Approach 2), and during a large synoptic sampling efforts concentrated across the watershed (AIMS Approach 3). Additional \\\"stretch\\\" samples were collected for TSS and AFDM at a tributary (TLC01) and downstream perennial monitoring site (TLP01), which are included in a separate file from the core TSS data from the Talladega research watershed. To measure TSS and AFDM concentrations, we collected 2- 3 replicates of unfiltered stream water in clean 1L Nalgene bottles after triple rinsing in the field, stored on ice, and brought to the lab for filtering. We brought samples back to the lab and filtered samples in 100mL batches through pre-ashed (550\\u2103 for one hour) and pre-weighed 47 mm Whatman GF/F filters. Once the sample was filtered, the filters were placed in a drying oven for at least 48 hours and weighed. TSS was calculated as the (dry weight (filter + tin + sample) - dry weight (filter + tin)) / volume filtered (L). Ash free dry mass (AFDM) was then calculated as (dry weight (filter + tin + sample) - ashed weight (filter + tin + sample)) / volume filtered (L).\", \"subject\": [\"AIMS\", \"Seston\", \"Talladega\",
