OCEARCH researchers first tagged the nearly 14-foot, 1,650-pound shark in January near the Florida\u2013Georgia border; their public tracker shows he has covered more than 4,300 miles since then. Contender reached waters near Newfoundland in late September and pinged around Nova Scotia before moving south; on Nov. 12 his tag showed him near New Jersey, with a last ping off Atlantic City the following night. The tracking group says the data help map white shark migration and behavior across seasons and regions.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>Contender is a male great white about 14 feet long and 1,650 pounds, tagged by OCEARCH in January near the Florida\u2013Georgia border.<\/li>\n<li>OCEARCH\u2019s tracker records show Contender has traveled more than 4,300 miles, reaching Newfoundland in late September and New Jersey waters by Nov. 12, 2025.<\/li>\n<li>Another OCEARCH-tagged shark, Ernst (female, ~12 ft, ~1,000 lb), was tracked traveling south to the Florida Keys after being tagged in Nova Scotia in October.<\/li>\n<li>OCEARCH tags typically transmit data for roughly five years, providing multi-season movement histories for individual sharks.<\/li>\n<li>Great white sightings increased in parts of Maine and Canadian waters this year, prompting some beach closures, though human-shark interactions remain rare.<\/li>\n<li>OCEARCH reports multiple shark species\u2014including tiger sharks and hammerheads\u2014moving along the Atlantic seaboard during seasonal shifts.<\/li>\n<\/ul>\n<h2>Background<\/h2>\n<p>OCEARCH, a research and data-collection organization, has been tagging large pelagic predators to study migration, health and population patterns. The group fitted Contender with a satellite-linked tag in January 2025, part of ongoing Atlantic expeditions that include tagging, biological sampling and public trackers. Historically, Atlantic great whites concentrate in cooler, prey-rich northern waters during summer and migrate south as fall and winter bring lower temperatures; researchers use tagging to document those seasonal shifts.<\/p>\n<p>Tagging programs gained public attention this year as northeastern Atlantic coastlines recorded heightened shark presence, notably off Maine and parts of Atlantic Canada, which led to localized beach restrictions and heightened monitoring. Scientists point to a mix of ecological drivers\u2014prey abundance, water temperature, and population recovery efforts\u2014as factors affecting distribution, but disentangling those drivers requires long-term, individual-based tracking data. OCEARCH and other groups publish trackers to inform both science and coastal managers.<\/p>\n<h2>Main Event<\/h2>\n<p>Contender\u2019s public movement history shows a northward progression along the U.S. East Coast through spring and summer, peaking with a presence near Newfoundland in late September 2025. In late October and early November his transmitter recorded multiple pings in and around Nova Scotia before the tag indicated a southerly transit. On Nov. 12 the tag placed Contender in New Jersey waters; by the next recorded update researchers noted him off Atlantic City.<\/p>\n<p>The OCEARCH tracker platform lists contemporaneous tracks for other tagged animals. Ernst, a 12-foot female white shark tagged during an October Nova Scotia expedition, moved southward to the Florida Keys after last being seen near the Florida\u2013Georgia border earlier in the year. OCEARCH highlighted both animals on social channels, describing their recent moves as part of broader seasonal migrations documented in 2025.<\/p>\n<p>Field teams emphasize that each satellite ping represents a geolocation and a time stamp that, together with other sensor data, helps reconstruct travel speed, stopover sites and habitat preferences. Because tags transmit intermittently, researchers combine those pings with environmental data and historical observations to interpret movement behavior. The group also notes that the publicly accessible tracker is a resource for researchers, managers and the interested public.<\/p>\n<h2>Analysis &#038; Implications<\/h2>\n<p>Contender\u2019s journey reinforces a recurring pattern in Atlantic great white ecology: long-distance seasonal movements between higher-latitude feeding areas and lower-latitude overwintering zones. For managers, detailed tracks of large individuals help identify corridors and aggregation zones that may merit monitoring or temporary mitigation measures when human-use and shark presence overlap. Continued returns of large adults to northern waters suggest prey availability there remains high enough to attract top predators.<\/p>\n<p>From a conservation perspective, telemetry data over multiple years can reveal population-level trends\u2014such as shifts in migration timing or range expansion\u2014that single-season sightings cannot. If northern foraging seasons lengthen or more individuals use inshore coastal habitats, coastal communities and policymakers may need to adapt public-safety messaging and beach management strategies. However, the evidence so far indicates sightings increased without a parallel rise in confirmed harmful interactions.<\/p>\n<p>Economically and ecologically, large white sharks are indicators of marine ecosystem health; their presence can signal robust prey populations, but also requires balancing conservation with coastal recreation and fisheries interests. Data from tags like Contender\u2019s help scientists advise regulators on where to prioritize monitoring, how to interpret seasonal variability, and what outreach is needed to keep beachgoers informed and safe.<\/p>\n<h2>Comparison &#038; Data<\/h2>\n<figure>\n<table>\n<thead>\n<tr>\n<th>Shark<\/th>\n<th>Sex<\/th>\n<th>Length (ft)<\/th>\n<th>Weight (lb)<\/th>\n<th>Noted locations (2025)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Contender<\/td>\n<td>Male<\/td>\n<td>~14<\/td>\n<td>1,650<\/td>\n<td>Florida\u2013Georgia border \u2192 Newfoundland \u2192 Nova Scotia \u2192 New Jersey<\/td>\n<\/tr>\n<tr>\n<td>Ernst<\/td>\n<td>Female<\/td>\n<td>~12<\/td>\n<td>~1,000<\/td>\n<td>Nova Scotia (tagged Oct) \u2192 Florida Keys<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>The table summarizes publicly reported metrics for two OCEARCH-tagged white sharks in 2025. While Contender\u2019s track covers more than 4,300 miles since January, Ernst\u2019s documented movement highlights a comparable seasonal southward transit after an October tagging in Nova Scotia. These snapshots illustrate individual variation within broader migratory patterns; tags that transmit for roughly five years offer opportunities to observe interannual changes.<\/p>\n<h2>Reactions &#038; Quotes<\/h2>\n<blockquote>\n<p>\u201cmaking moves\u201d<\/p>\n<p><cite>OCEARCH (social media)<\/cite><\/p><\/blockquote>\n<p>OCEARCH used the phrase above when describing Contender\u2019s north\u2013south movements, noting the animal\u2019s repeated pings as it shifted latitude.

Tags may also record depth, temperature and dive profiles, which researchers combine with oceanographic data to infer habitat preferences and foraging behavior. Because transmissions are intermittent and can be influenced by tag attachment, battery life and surfacing behavior, scientists interpret ping series as part of a larger analytical framework that includes historical observations and environmental models.<\/p>\n<\/details>\n<\/aside>\n<\/h2>\n<h2>Unconfirmed<\/h2>\n<ul>\n<li>Whether recent increases in sightings are driven primarily by rising coastal water temperatures, prey distribution shifts, or improved observation effort remains unresolved.<\/li>\n<li>The long-term population trend for Atlantic great whites is still uncertain; multi-year tag records are needed to confirm whether 2025 reflects a statistically significant increase in abundance.<\/li>\n<li>Exact behavioral drivers for Contender\u2019s specific stopovers in Nova Scotia and Newfoundland (e.g., particular prey aggregations) have not been directly confirmed by diet or stomach-content data.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>Contender\u2019s return to New Jersey waters after a summer in Canadian latitudes underscores the broad, seasonally driven movements of Atlantic great whites and the value of individual-based telemetry. The roughly 4,300-mile path recorded since January 2025 provides a high-resolution glimpse of one large male\u2019s range, informing both scientific understanding and coastal management decisions. Although sightings rose in parts of the Northeast this year, documented harmful human\u2013shark interactions have remained uncommon.<\/p>\n<p>Going forward, sustained tagging, coupled with environmental and prey surveys, will be essential to discern whether recent patterns reflect temporary variability or longer-term shifts in distribution. For coastal communities, the immediate takeaway is clear: improved monitoring and public communication\u2014grounded in data\u2014can reduce risk while allowing scientists to gather the information needed to manage both shark conservation and beach safety.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.cbsnews.com\/news\/atlantic-ocean-largest-great-white-shark-contender-ocearch\/\" target=\"_blank\" rel=\"noopener\">CBS News (news outlet)<\/a><\/li>\n<li><a href=\"https:\/\/www.ocearch.org\/\" target=\"_blank\" rel=\"noopener\">OCEARCH Tracker (research organization; tracking platform)<\/a><\/li>\n<li><a href=\"https:\/\/www.instagram.com\/ocearch\/\" target=\"_blank\" rel=\"noopener\">OCEARCH Instagram (organization social channel)<\/a><\/li>\n<li><a href=\"https:\/\/www.fisheries.noaa.gov\/\" target=\"_blank\" rel=\"noopener\">NOAA Fisheries (official government resource)<\/a><\/li>\n<\/ul>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Updated November 13, 2025 Lead The largest male great white shark ever tagged in the Atlantic, nicknamed Contender, has reappeared off southern New Jersey after a northerly summer that took him to Canadian waters.
