Surface sediment samples for analysis of grain size and organic matter content were collected at each site within 1 m radius of CSM measurements using a spatula to scrape the top 2-3 cm of sediments. The combustible organic matter content (loss on ignition, LOI) of the surface sediments was determined after: (1) drying at 60°C for 24 h until no weight change occurred; (2) placing in oven at 450°C for 16 h. For grain size analysis, the coarse and the fine grain size distributions were processed with Gradistat (Blott and Pye, 2001) to compute median grain size (d50), mean grain size, and sorting using the geometric moment method. The sorting is calculated similarly to a standard deviation. Cross-shore transect B was sampled in November 2017 for which, the data is presented here. The data for summer 2016, summer 2017, and summer 2018 was published in the context of annual variations in sediment biostabilization (Waqas et al., 2019, doi:10.1594/PANGAEA.911771) Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Neumeier Urs Rochon André rochona@agc.bio.ns.ca 2020 Seasonal changes in sediment erodibility associated with biostabilization in a subarctic intertidal environment, St. Lawrence Estuary, Canada journal article Estuarine, Coastal and Shelf Science 245 https://doi.org/10.1016/j.ecss.2020.106935 106935 Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Neumeier Urs Rochon André rochona@agc.bio.ns.ca 2020 Spatial and annual patterns of grain size and organic matter content in an intertidal area, St. Lawrence Estuary, Canada dataset https://doi.org/10.1594/PANGAEA.911771 -68.56915008 -68.56447022 48.44233654 48.45070791 -68.56648066111111 48.44590988777778 -0.917 2.273 not specified St.Lawrence_B1 B1 48.44233654 -68.56447022 St. Lawrence Estuary, lower 2.273 Multiple investigations MULT St.Lawrence_B2 B2 48.44296507 -68.56491458 St. Lawrence Estuary, lower 1.649 Multiple investigations MULT St.Lawrence_B3 B3 48.44375217 -68.56526994 St. Lawrence Estuary, lower 0.481 Multiple investigations MULT St.Lawrence_B4 B4 48.44459387 -68.56570215 St. Lawrence Estuary, lower 0.388 Multiple investigations MULT St.Lawrence_B5 B5 48.44545339 -68.56627805 St. Lawrence Estuary, lower 0.024 Multiple investigations MULT St.Lawrence_B6 B6 48.4462816 -68.56668081 St. Lawrence Estuary, lower -0.213 Multiple investigations MULT St.Lawrence_B7 B7 48.4478659 -68.56753326 St. Lawrence Estuary, lower -0.503 Multiple investigations MULT St.Lawrence_B8 B8 48.44923254 -68.56832686 St. Lawrence Estuary, lower -0.673 Multiple investigations MULT St.Lawrence_B9 B9 48.45070791 -68.56915008 St. Lawrence Estuary, lower -0.917 Multiple investigations MULT 72 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Event label Event Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Event Latitude of event Latitude Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Latitude Longitude of event Longitude Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Longitude Elevation of event Elevation m Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Elevation [m] Campaign Campaign Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Campaign Gravel Gravel % gravel http://purl.obolibrary.org/obo/ENVO_01000018 Dimensionless Ratio ψ CamsizerXT (Retsch Technology), statistical analysis GRADISTAT package (Blott and Pye, 2001) https://doi.org/10.1002/esp.261 Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Gravel [%] Sand Sand % sand Dimensionless Ratio ψ CamsizerXT (Retsch Technology), statistical analysis GRADISTAT package (Blott and Pye, 2001) https://doi.org/10.1002/esp.261 Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Sand [%] Silt Silt % silt http://purl.obolibrary.org/obo/ENVO_01000016 Dimensionless Ratio ψ CamsizerXT (Retsch Technology), statistical analysis GRADISTAT package (Blott and Pye, 2001) https://doi.org/10.1002/esp.261 Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Silt [%] Clay minerals Clay min % clay http://purl.obolibrary.org/obo/ENVO_00002982 Dimensionless Ratio ψ CamsizerXT (Retsch Technology), statistical analysis GRADISTAT package (Blott and Pye, 2001) https://doi.org/10.1002/esp.261 Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Clay min [%] Grain size, mean Grain size mean µm size http://purl.obolibrary.org/obo/PATO_0000117 mean Length L http://dbpedia.org/resource/Length Geometric method of moments Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Grain size mean [µm] Median, grain size D50 µm size http://purl.obolibrary.org/obo/PATO_0000117 Length L http://dbpedia.org/resource/Length Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 D50 [µm] Sorting Sort Geometric method of moments Waqas Atif atifwqs@hotmail.com 0000-0002-6160-0961 Sort citable Grain Size Intertidal cohesive sediments organic matter author21926 author65447 author73814 event2924384 event2924385 event2924386 event2924387 event2924388 event2924389 event2924390 event2924391 event2924392 geocode1600 geocode1601 geocode8128 journal5142 license21 method10272 method10667 method9293 param130689 param134113 param153 param155 param25665 param26119 param5194 param5349 pi73814 ref105200 refds911771 term1073201 term1073204 term1073206 term1073207 term21205 term40958 term42093 term43794 term43863 term47485 term48857 term52414 topotype1
