After this project, two more CURBY systems were developed for use in NOAA\u2019s 2022-2023 Columbia River tidal currents surveys.<\/p>\n<p>Over the same\u00a0time period, the original CURBY buoy was re-deployed off the coast of Savannah, GA, in order to support NOAA\u2019s Savannah River tidal currents survey. Data collected by NOAA\u2019s tidal current surveys are used to update the Nation\u2019s tidal current predictions in a given region.<\/p>\n<p>\u201c[The Columbia River], in particular, is a sandy bottom river with sand waves that reach 10 to 15 feet in height and regularly sweep through the river\u2019s bottom. Many of our typical current sensor deployment setups that we would otherwise use. For example, bottom mount sensors were not appropriate for our Columbia River currents survey,\u201d elaborates Heilman.<\/p>\n<div id=\"attachment_38427\" style=\"width: 950px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38427\" class=\"wp-image-38427 size-full\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/06\/IMG_0737_ForWeb.jpg\" alt=\"The CURBY real-time buoy is easily deployed from small vessels like NOAA\u2019s R\/V Tornado, pictured here on the left.\" width=\"940\" height=\"940\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0737_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0737_ForWeb-300x300.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0737_ForWeb-600x600.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0737_ForWeb-150x150.jpg 150w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0737_ForWeb-768x768.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-38427\" class=\"wp-caption-text\"><span style=\"color: #808080;\">The CURBY real-time buoy is easily deployed from small vessels like NOAA\u2019s R\/V Tornado, pictured here on the left.

According to the CO-OPS team working on the deployment, the CURBY buoy was the ideal solution to deliver quick, accurate results.<\/p>\n<p>With an already assembled CURBY system positioned at the CO-OPS Chesapeake, VA field office, NOAA was able to quickly\u00a0prepare the instrument for deployment and get\u00a0it\u00a0deployed in Baltimore only days later.<\/p>\n<div id=\"attachment_38422\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38422\" class=\"wp-image-38422 size-full\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/06\/Image-4_-CURBY-with-NOAA-staff_ForWeb.jpg\" alt=\"CURBY with NOAA CO-OPS staff members Robert Heitsenrether, Grace Gray, Warren Krug, Winston Hensley, and the Office of Response and Restoration\u2019s Charlie Henry. \" width=\"600\" height=\"606\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/Image-4_-CURBY-with-NOAA-staff_ForWeb.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/Image-4_-CURBY-with-NOAA-staff_ForWeb-297x300.jpg 297w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-38422\" class=\"wp-caption-text\"><span style=\"color: #808080;\">CURBY with NOAA CO-OPS staff members Robert Heitsenrether, Grace Gray, Warren Krug, Winston Hensley, and the Office of Response and Restoration\u2019s Charlie Henry. (Credit: NOAA)<\/span><\/p><\/div>\n<p>The current and meteorological data\u00a0gathered by the system\u00a0in part to support,\u00a0dive and salvage operations, and also to\u00a0provide navigational support. Already having a designed and tested system to deploy was one of the main reasons CO-OPS was contacted for the project as it allowed for quick deployment.<\/p>\n<p>Because the CURBY needed to be in the water within a matter of days, the CO-OPS team had to expedite a lot of the paperwork and setup, which they could usually spend weeks to months preparing. Permits and environmental compliance documents all had to be completed and approved before the system was deployed.<\/p>\n<p>Deploying the buoy near Baltimore at such short-notice raised a number of logistical issues. Although compact, the CURBY is generally deployed from a vessel with lifting capability. In Baltimore, the team had limited lifting capability to offload, assemble, and prepare the buoy for deployment\u2014making this deployment slightly more challenging than usual.<\/p>\n<p>An unfamiliar launch site, boat ramp, and inclement weather conditions also presented a challenge during the buoy\u2019s deployment. Ultimately, the deployment was a success, and the CURBY was moored in its current position by NOAA\u2019s 25-foot vessel R\/V Tornado.<\/p>\n<p>Before the buoy was deployed, there was a great deal of discussion surrounding its ultimate\u00a0location. This detail can impact how the instrumentation is programmed and the naming of the system in NOAA\u2019s database. The goal of this\u00a0project was to provide\u00a0real-time data to the public and recovery partners as soon as possible following the buoy\u2019s deployment.<\/p>\n<div id=\"attachment_38425\" style=\"width: 950px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38425\" class=\"wp-image-38425 size-full\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/06\/IMG_0566_ForWeb.jpg\" alt=\"The currents real-time buoy, CURBY, is assembled on-site by a small team of NOAA engineers and oceanographers. \" width=\"940\" height=\"729\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0566_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0566_ForWeb-300x233.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0566_ForWeb-600x465.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/06\/IMG_0566_ForWeb-768x596.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-38425\" class=\"wp-caption-text\"><span style=\"color: #808080;\">The CURBY buoy is assembled on-site by a small team of NOAA engineers and oceanographers.
