Number of variables: 13 2. Number of cases/rows: 97 3. Missing data codes: None 4. Variable List A. Name: Sample Date Description: Date the data was collected B. Name: Site # Description: Site number associated with the data for that sample day. Site numbers 1-10 were reused each sampling date, but the same sites were not visited from day to day, so Site 1 is not in the same location every time it appears. C. Name: Latitude Description: Latitude for the site the data was collected from (decimal degrees) D. Name: Longitude Description: Longitude for the site the data was collected from (decimal degrees) E. Name: Total Corbicula Description: Total number of C. fluminea recovered from the sample site F. Name: Live Corbicula Description: Number of C. fluminea recovered from the sample site that were alive at the time of sampling G. Name: Dead Corbicula Description: Number of C. fluminea recovered from the sample site that were dead (or empty shells) at the time of sampling H. Name: % Live Description: Calculation of the percent of the total recovered C. fluminea that were living at the time of sampling (if any C. fluminea were recovered) I. Name: Temperature (deg C) Description: Temperature at the water-sediment interface at the sample site (for data collected December 2020-March 2021) or centrally in the study area (for data collected April 2021-September 2021). Data collected centrally is recorded on Site 1, but may not correspond to those exact coordinates J. Name: Water Depth (inches) Description: Water depth at the sample site K. Name: Ice Thickness (inches) Description: Ice thickness at the sample site (ice only present December 2020 - March 2021) L. Name: Dissolved Oxygen (mg/L) Description: Dissolved oxygen at the water-sediment interface at the sample site (for data collected December 2020-March 2021) or centrally in the study area (for data collected April 2021-September 2021).

Number of variables: 5 2. Number of cases/rows: 501 3. Missing data codes: none 4. Variable List A. Name: Season Description: Indicated if collection happened during through-ice sampling (cold water) or open water sampling (warm water) B. Name: Sample Month Description: Month the clam was collected in B. Name: Site # Description: Site number associated with the data for that sample day. Site numbers 1-10 were reused each sampling date, but the same sites were not visited from day to day, so Site 1 is not in the same location every time it appears. B. Name: Size (mm) Description: Shell width of the clam (measured from anterior to posterior) B. Name: Life status Description: Indication of if the clam was living or dead at the time of collection. Dead included empty shells with no tissue present. ---------------------------------------- DATA-SPECIFIC INFORMATION FOR: Corbicula_Surveillance_Data_Extended_Sampling_Data.csv ----------------------------------------- 1.
