The warming phase, known as El Ni\u00f1o, and the cooling phase, known as La Ni\u00f1a, affect weather patterns across different coastlines depending on the cycle.<\/p>\n<p>During these periods, coastal erosion can also intensify, shifting sand away from beaches and threatening beachfront homes and habitats. But scientists haven&#8217;t been able to study this broadly using conventional coastal monitoring techniques, which have been limited to on-ground observations on just a few beaches.<\/p>\n<p>&#8220;Scientists have known beaches respond to ENSO cycles for decades, but we&#8217;ve only been able to paint a small picture of this from a few sporadic beach monitoring sites,&#8221; says Dr. Mitchell Harley, co-author of the study from UNSW&#8217;s Water Research Laboratory at the School of Civil &amp; Environmental Engineering. &#8220;For this research, we were able to take a completely different angle to complete the bigger picture of how climate cycles impact entire Pacific coasts.&#8221;\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Observing_coastal_changes_from_the_cosmos\"><\/span>Observing coastal changes from the cosmos<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Satellites orbiting the Earth have captured images of the world&#8217;s coastlines at regular intervals for almost forty years. The researchers developed a new open-source tool called CoastSat, which combines image processing and machine learning algorithms to extract information from every pixel about thousands of sandy beaches along the Pacific rim.<\/p>\n<p>&#8220;The tool automatically maps the position of the interface between the sand and water. Doing this over multiple images and beaches, and correcting for the tide, we can discover changes in the coastline over a large temporal and spatial scale and how this correlates with ENSO cycles,&#8221; says Dr. Kilian Vos, lead author of the study from the Water Research Laboratory.<\/p>\n<figure class=\"mb-4\" itemscope=\"\" itemtype=\"http:\/\/schema.org\/VideoObject\"><meta itemprop=\"name\" content=\"Beach erosion: satellites reveal how climate cycles impact coastlines\"\/><meta itemprop=\"url\" content=\"https:\/\/www.youtube.com\/watch\/?v=D3oqRze4rDc\"\/><meta itemprop=\"description\" content=\"Credit: University of New South Wales\"\/><meta itemprop=\"uploadDate\" content=\"2023-02-10T08:02:17-05:00\"\/><meta itemprop=\"embedUrl\" content=\"https:\/\/www.youtube.com\/embed\/D3oqRze4rDc\"\/><meta itemprop=\"thumbnailUrl\" content=\"https:\/\/img.youtube.com\/vi\/D3oqRze4rDc\/maxresdefault.jpg\"\/><\/p>\n<p>\n             <iframe loading=\"lazy\" title=\"CoastSat demonstration\" width=\"640\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/D3oqRze4rDc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><figcaption class=\"text-darken text-low-up mt-4\" itemprop=\"caption\">Credit: University of New South Wales<\/figcaption><\/figure>\n<p>Using the tool, the researchers processed 38 years of Landsat satellite photos to find correlations in beach width and El Ni\u00f1o and La Ni\u00f1a cycles across more than 8000km of sandy coastline, from the east coast of Australia to the west coast of California and down to Chile.<\/p>\n<p>They found that beaches on the southeast coast of Australia narrow during prolonged La Ni\u00f1a, while they widen\u2014or accrete\u2014during El Ni\u00f1o periods.
