To accurately model fluvial carbon and\nfreshwater export from rapidly changing river catchments as well as assess impacts of future change on the Arctic shelf and coastal ecosystems, we need\nto understand the sea floor characteristics and topographic variety of the\ncoastal zones. To date, digital bathymetrical data from the poorly\naccessible, shallow, and large areas of the eastern Siberian Arctic shelves\nare sparse. We have digitized bathymetrical information for nearly 75\u2009000\nlocations from large-scale (1:25\u2009000\u20131:500\u2009000) current and historical\nnautical maps of the Lena Delta and the Kolyma Gulf region in northeastern\nSiberia. We present the first detailed and seamless digital models of\ncoastal zone bathymetry for both delta and gulf regions in 50 and 200\u2009m spatial resolution. We validated the resulting bathymetry layers using a\ncombination of our own water depth measurements and a collection of\navailable depth measurements, which showed a strong correlation (\n                    <jats:italic>r<\/jats:italic>\n                    <jats:italic>&gt;<\/jats:italic>\n                    0.9). Our bathymetrical models will serve as an input for a\nhigh-resolution coupled hydrodynamic\u2013ecosystem model to better quantify\nfluvial and coastal carbon fluxes to the Arctic Ocean, but they may be useful for\na range of other studies related to Arctic delta and near-shore dynamics\nsuch as modeling of submarine permafrost, near-shore sea ice, or shelf\nsediment transport. The new digital high-resolution bathymetry products are available on the PANGAEA data set repository for the Lena Delta (https:\/\/doi.org\/10.1594\/PANGAEA.934045; Fuchs et al., 2021a) and Kolyma Gulf region (https:\/\/doi.org\/10.1594\/PANGAEA.934049; Fuchs et al., 2021b), respectively. Likewise, the depth validation data are available on PANGAEA as well (https:\/\/doi.org\/10.1594\/PANGAEA.933187; Fuchs et al., 2021c).\n                  <\/jats:p>","DOI":"10.5194\/essd-14-2279-2022","type":"journal-article","created":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T02:23:21Z","timestamp":1652408601000},"page":"2279-2301","source":"Crossref","is-referenced-by-count":6,"title":["High-resolution bathymetry models for the Lena Delta and Kolyma Gulf coastal zones"],"prefix":"10.5194","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3529-8284","authenticated-orcid":false,"given":"Matthias","family":"Fuchs","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"},{"role":"corresponding-author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6921-5697","authenticated-orcid":false,"given":"Juri","family":"Palmtag","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5844-6318","authenticated-orcid":false,"given":"Bennet","family":"Juhls","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9849-4712","authenticated-orcid":false,"given":"Pier Paul","family":"Overduin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5895-2141","authenticated-orcid":false,"given":"Guido","family":"Grosse","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Abdelwahab","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4255-9406","authenticated-orcid":false,"given":"Michael","family":"Bedington","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3692-1800","authenticated-orcid":false,"given":"Tina","family":"Sanders","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5659-8318","authenticated-orcid":false,"given":"Olga","family":"Ogneva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5370-427X","authenticated-orcid":false,"given":"Irina V.","family":"Fedorova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikita S.","family":"Zimov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6221-3533","authenticated-orcid":false,"given":"Paul J.","family":"Mann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4678-4982","authenticated-orcid":false,"given":"Jens","family":"Strauss","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3145","published-online":{"date-parts":[[2022,5,13]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Anand, P. and Kumar, P.: Influence of Bathymetry on the Performance of Regional Scale Model, Defence Sci.
