The system uses light penetration and reflection in the water to make measurements and estimate variations in ocean floor depths. SDB provides several advantages over other techniques used to map the seafloor (e.g., cost-effectiveness, global coverage, and faster data acquisition). On the other hand, SDB can be limited by water clarity, spatial resolution of the remote sensing measurement, and accuracy, depending on the method and satellite platform\/instrument.  These limitations notwithstanding, SDB can be used in a wide variety of applications,  e.g.,  coastal zone management, navigation and safety, marine habitat monitoring, and disaster response. ICESat-2 has become a major contributor to SDB, with over 2000 journal article references to this topic to date<strong>.<\/strong> Now is the time to think about the state-of-the-art and additional capabilities of SDB for the future.<\/p>\n<p>To help stimulate such thinking, the NASA ICESat-2 applications team hosted a one-day workshop on March 17, 2025. The workshop focused on the principles and methods for SDB. Held in conjunction with the annual <a href=\"https:\/\/www.thsoa.org\/us-hydro-2025\" rel=\"noopener\">US-Hydro meeting<\/a> on March 17\u201320, 2025 at the Wilmington Convention Center in Wilmington, NC, the meeting was hosted by the Hydrographic Society of America. During the workshop the applications team brought together SDB end-users, algorithm developers, operators, and decision makers to discuss the current state and future needs of satellite bathymetry for the community. The objective of this workshop was to provide a space to foster collaboration and conceptualization of SDB applications not yet exploited and to allow for networking to foster synergies and collaborations between different sectors.<\/p>\n<p><strong>Meeting Overview<\/strong><\/p>\n<p>The workshop provided an opportunity for members from government, academia, and private sectors to share their SDB research, applications, and data fusion activities to support decision making and policy support across a wide range of activities. Presenters highlighted SDB principles, methods, and tools for SDB, an introduction of the <a href=\"https:\/\/nsidc.org\/data\/atl24\/versions\/1\" rel=\"noopener\">new ICESat-2 bathymetric data product<\/a> (ATL24), which is now available through the <a href=\"https:\/\/nsidc.org\/home\" rel=\"noopener\">National Snow and Ice Data Center<\/a> (NSIDC). During the workshop, the ICESat-2 team delivered a live demonstration of a web service for science data processing. Toward the end of the day, the applications team opened an opportunity for attendees to gather and discuss various topics related to SDB. This portion of the meeting was also available to online participation via Webex Webinars, which broadened the discussion.<\/p>\n<p><em>Meeting Goal<\/em><\/p>\n<p>The workshop offered a set of plenary presentations and discussions. During the plenary talks, participants provided an overview of Earth observation and SDB principles, existing methods and tools, an introduction to the newest ICESat-2 bathymetry product ATL24, a demonstration of the use of the webservice <a href=\"https:\/\/slideruleearth.io\/\" rel=\"noopener\">SlideRule Earth<\/a>, and opportunities for open discission, asking questions and developing collaborations.<\/p>\n<p><em>Meeting and Summary Format<\/em><\/p>\n<p>The agenda of the SDB workshop was intended to bring together SDB end-users, including ICESat-2 application developers, satellite operators, and decision makers from both government and non-governmental entities to discuss the current state and future needs of the community. The workshop consisted of six sessions that covered various topics of SDB. This report is organized according to the topical focus of the plenary presentations with a brief narrative summary of each presentation included. The discussions that followed were not recorded and are not included in the report. The last section of this report consists of conclusions and future steps.

(SSAI)\u2014<em>ICESat-2 Mission Applications Lead<\/em>] organized the workshop and served as the host for the event.

Smith began by relaying the history of satellite-derived bathymetry, which began with a collaboration between NASA and Jacques Cousteau in 1975, in which Cousteau used Landsat 1 data, as well as <em>in situ<\/em> data, to calculate bathymetry to a depth of 22 m (72 ft) in the Bahamas. Smith then described the five broad  methodologies and their basic concepts for deriving bathymetry from remote sensing: radar altimetry, bottom reflectance, wave kinematics, laser altimetry, and space-based photogrammetry \u2013 see<strong> Figure 2<\/strong>. He then introduced the broad methodologies, most commonly used satellite sensors, the capabilities and limitations of each sensor, and the role of ICESat-2 in satellite bathymetry.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=1440&#038;h=608&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"1440\" height=\"608\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=1440&#038;h=608&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"ICESat-2 figure 2\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" loading=\"lazy\" srcset=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=1440&#038;h=608&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1440w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=300&#038;h=127&#038;fit=crop&#038;crop=faces%2Cfocalpoint 300w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=768&#038;h=324&#038;fit=crop&#038;crop=faces%2Cfocalpoint 768w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=1024&#038;h=432&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1024w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=400&#038;h=169&#038;fit=crop&#038;crop=faces%2Cfocalpoint 400w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=600&#038;h=253&#038;fit=crop&#038;crop=faces%2Cfocalpoint 600w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=900&#038;h=380&#038;fit=crop&#038;crop=faces%2Cfocalpoint 900w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-spring\/icesat-2\/ICESat2-figure_2.png?w=1200&#038;h=507&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1200w\" sizes=\"auto, (max-width: 1440px) 100vw, 1440px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\"><strong>Figure 2<\/strong>.

During this presentation, Lowell provided examples of accuracy assessments and uncertainty through the comparison of ground measurement of coastal bathymetry to those modeled from satellite data.<\/p>\n<p><strong>Conclusion<\/strong> <\/p>\n<p>The ICESat-2 Satellite Bathymetry workshop fostered discussion and collaboration around the topic of SDB methods. The plenary speakers presented the state-of-the-art methods used by different sectors and organizations, including government and private entities. With the release of ATL24, ICESat-2\u2019s new bathymetry product, it was prudent to have a conversation about new and upcoming capabilities for all methods and measurements of satellite bathymetry. Both in-person and online participants were provided with the opportunity to learn, ask questions, and discuss potential applications in their own research. The ICESat-2 applications team hopes to host more events to ensure the growth of this field to maximize the capabilities of ICESat-2 and other Earth Observing systems.<\/p>\n<div id=\"\" class=\"nasa-gb-align-full width-full maxw-full padding-x-3 padding-y-0 nasa_template_article_a hds-module hds-module-full alignfull wp-block-nasa-blocks-credits-and-details\">\n<section class=\"padding-x-0 padding-top-5 padding-bottom-2 desktop:padding-top-7 desktop:padding-bottom-9\">\n<div class=\"grid-row grid-container maxw-widescreen padding-0\">\n<div class=\"grid-col-12 desktop:grid-col-2 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n<div class=\"padding-top-3 border-top-1px border-color-carbon-black\">\n<div class=\"margin-bottom-2\">\n<h2 class=\"heading-14\">Share<\/h2>\n<\/p>\n<\/div>\n<div class=\"padding-bottom-2\">\n<ul class=\"social-icons social-icons-round\">\n<li class=\"social-icon social-icon-x\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/x.com\/intent\/tweet?via=NASA&#038;text=ICESat-2%20Applications%20Team%20Hosts%20Satellite%20Bathymetry%20Workshop&#038;%23038;url=https%3A%2F%2Fscience.nasa.gov%2Fscience-research%2Fearth-science%2Ficesat-2-applications-team-hosts-satellite-bathymetry-workshop%2F\" aria-label=\"Share on X.\"><br \/>\n\t\t\t\t\t\t\t\t<svg width=\"1200\" height=\"1227\" viewBox=\"0 0 1200 1227\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M714.163 519.284L1160.89 0H1055.03L667.137 450.887L357.328 0H0L468.492 681.821L0 1226.37H105.866L515.491 750.218L842.672 1226.37H1200L714.137 519.284H714.163ZM569.165 687.828L521.697 619.934L144.011 79.6944H306.615L611.412 515.685L658.88 583.579L1055.08 1150.3H892.476L569.165 687.854V687.828Z\" fill=\"white\"\/><\/svg><br \/>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n<li class=\"social-icon social-icon-facebook\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.facebook.com\/sharer.php?u=https%3A%2F%2Fscience.nasa.gov%2Fscience-research%2Fearth-science%2Ficesat-2-applications-team-hosts-satellite-bathymetry-workshop%2F\" aria-label=\"Share on Facebook.\" rel=\"noopener\"><br \/>\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 24 24\" aria-hidden=\"true\"><path d=\"M9 8h-3v4h3v12h5v-12h3.642l.358-4h-4v-1.667c0-.955.192-1.333 1.115-1.333h2.885v-5h-3.808c-3.596 0-5.192 1.583-5.192 4.615v3.385z\"\/><\/svg><br \/>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n<li class=\"social-icon social-icon-linkedin\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.linkedin.com\/shareArticle?mini=true&#038;url=https%3A%2F%2Fscience.nasa.gov%2Fscience-research%2Fearth-science%2Ficesat-2-applications-team-hosts-satellite-bathymetry-workshop%2F\" aria-label=\"Share on LinkedIn.\" rel=\"noopener\"><br \/>\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 24 24\" aria-hidden=\"true\"><path d=\"M4.98 3.5c0 1.381-1.11 2.5-2.48 2.5s-2.48-1.119-2.48-2.5c0-1.38 1.11-2.5 2.48-2.5s2.48 1.12 2.48 2.5zm.02 4.5h-5v16h5v-16zm7.982 0h-4.968v16h4.969v-8.399c0-4.67 6.029-5.052 6.029 0v8.399h4.988v-10.131c0-7.88-8.922-7.593-11.018-3.714v-2.155z\"\/><\/svg><br \/>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n<li class=\"social-icon social-icon-rss\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/science.nasa.gov\/feed\/\" aria-label=\"Subscribe to RSS feed.\"><br \/>\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 800 800\" aria-hidden=\"true\"><path d=\"M493 652H392c0-134-111-244-244-244V307c189 0 345 156 345 345zm71 0c0-228-188-416-416-416V132c285 0 520 235 520 520z\"\/><circle cx=\"219\" cy=\"581\" r=\"71\"\/><\/svg><br \/>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"grid-col-12 desktop:grid-col-5 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n<div class=\"padding-top-3 border-top-1px border-color-carbon-black\">\n<div class=\"margin-bottom-2\">\n<h2 class=\"heading-14\">Details<\/h2>\n<\/p>\n<\/div>\n<div class=\"grid-row margin-bottom-3\">\n<div class=\"grid-col-4\">\n<div class=\"subheading\">Last Updated<\/div>\n<\/p>\n<\/div>\n<div class=\"grid-col-8\">Jun 05, 2025<\/div>\n<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"grid-col-12 desktop:grid-col-5 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n<div class=\"padding-top-3 border-top-1px border-color-carbon-black \">\n<div class=\"margin-bottom-2\">\n<h2 class=\"heading-14\">Related Terms<\/h2>\n<\/div>\n<ul class=\"article-tags\">\n<li class=\"article-tag\"><a href=\"https:\/\/science.nasa.gov\/earth\/\" rel=\"noopener\">Earth Science<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Introduction On September 15, 2018, the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission launched from Vandenberg Air Force Base and began its journey to provide spatially dense and fine precision global measurements of our Earth\u2019s surface elevation.
