PASTA will use this value to check the integrity of the data it downloads from your site. In addition, PASTA is planning to compare the contributor-supplied checksum/hash value documented
in the physical/authentication element to the checksum/hash value of this entity downloaded from previous revisions of this data package. If PASTA already has a copy of this entity, it will be able
to avoid an unnecessary download of the entity from your site, resulting in faster processing of the new data package revision when you update it in PASTA.
Add a physical/authentication element and store the entity checksum or hash value in it using a method such as MD5 or SHA-1.

Check for presence of an entity size element
Look for entity size element as a prep for checking congruence, and if not present, generate a warn. Note that to be most useful (i.e, to check congruence), entity size should contain the most precise measure of size, which is "byte" (the default unit); however, the presence or name of the entity size unit is NOT checked.
Entity size is present. If unit="byte" or unit is omitted (default = byte), then congruence can be checked.
Found entity size element with value of 55034 and size unit specified as 'bytes'. Please note that a size element specified with a unit other than 'byte' will not be tested for congruence.
Examining the entity size is prep for checking congruence. Including the element is best practice, and if not present, a warn is generated. To be most useful, entity size should contain the most precise measure of size, which is "byte" (the default unit).

We note that the Depth_m likely includes marginal error over the course of the dataset, but this error is unquantified., Samples were collected using a Van Dorn water sampler and frozen in acid-washed 125 mL polypropylene bottles prior to analysis. TP samples were digested with alkaline persulfate (Patton and Kryskalla 2003) and then analyzed colorimetrically using flow injection analysis (APHA 2005). TP was analyzed using the ascorbic acid method (Murphy and Riley 1962) on a Lachat Instruments XYZ Autosampler ASX 520 Series and QuikChem Series 8500 (Lachat ASX 520 Series, Lachat Instruments, Loveland, Colorado, USA)., 10 ug/L, Additional documentation in published data product, Samples were collected using a Van Dorn water sampler and frozen in acid-washed 125 mL polypropylene bottles prior to analysis. TN samples were digested with alkaline persulfate (Patton and Kryskalla 2003) and then analyzed colorimetrically using flow injection analysis (APHA 2005). TN was analyzed using the cadmium reduction method (APHA 1998) on a Lachat Instruments XYZ Autosampler ASX 520 Series and QuikChem Series 8500 (Lachat ASX 520 Series, Lachat Instruments, Loveland, Colorado, USA)., 75 ug/L, Additional documentation in published data product, Unfiltered water samples were collected with a Van Dorn water sampler and stored in opaque 2-L high-density polyethylene bottles. Samples were refrigerated and filtered within 48 hours of collection with GF/C filters and filters were immediately frozen after filtration. Samples were generally analyzed within 4 months of collection date. Samples were extracted using a 96% ethanol solution at room temperature for 3-24 hours (Wasmund et al. 2006) and then analyzed by spectrophotometric analysis. To quantify the concentration of phaeophytin within the sample, the analysis adopts the acidification recommendation of Parker et al. (2016), in which 240 microliters of 0.1 N HCl was added to the sample. The sample was homogenized and left to sit for 90 seconds for samples analyzed through 2018, or 120 seconds for samples analyzed after 2019. Samples were quantified using the monochromatic spectrophotometric method for chlorophyll a after correction for the presence of pheopigments, to provide a metric of "live" phytoplankton at the time of collection (Lorenzen 1967). The phaeophytin concentration (a metric of "dead" but still fluorescing phytoplankton) is also reported. In 2014, total chlorophyll a was corrected for phaeophytin but values for phaeophytin were lost during digitization. Samples were deemed below detection based on the difference between values quantified before and after acidification. Both extraction and analysis were performed in the absence of direct light to prevent the degradation of chlorophyll a. Samples collected were not always analyzed, leading to occasional incomplete water column profiles for certain dates within the dataset., , , DOC samples were collected using a Van Dorn water sampler and were filtered with a 0.7 um glass fiber filter (Thomas Scientific GF/F) before being stored in acid-washed 125 mL polypropylene bottles. Samples were generally analyzed within six months of collection date. DOC was analyzed using the persulfate catalytic method (Brenton and Arnett 1993) on a TOCA 1010 from OI Analytical from 2013-2016 (OI Analytical 1010 Total Organic Carbon Analyzer with 1051 autosampler, College Station, TX USA) and on a Vario TOC Cube from Elementar from 2016-2021 (vario TOC cube, Elementar Analysensysteme GmbH, Hanau, Germany)., Additional notes in published data product, Bathymetric data were collected using an Acoustic Doppler Current Profiler (ADCP) and processed using WinRiver II and ArcGIS., Collected in July 2014 when the reservoir was at approximately full pond, Water level decreased from 13 to 10 meters between 2013 and 2021, Eutrophic, Dimictic, TEMP and OXYGEN: https://portal.edirepository.org/nis/mapbrowse?packageid=edi.200.12 Nutrients and carbon: https://portal.edirepository.org/nis/metadataviewer?packageid=edi.199.10 BATHYMETRY: https://portal.edirepository.org/nis/mapbrowse?packageid=edi.1254.1 Chl-a: https://portal.edirepository.org/nis/mapbrowse?scope=edi&identifier=555&revision=2]]>
