Abstract
Glacial millennial‐scale paleoceanographic changes in the Southeast Pacific and the adjacent Southern Ocean are poorly known due to the scarcity of well‐dated and high resolution sediment records. Here we present new surface water records from sediment core MD07‐3128 recovered at 53°S off the Pacific entrance of the Strait of Magellan. The alkenone‐derived sea surface temperature (SST) record reveals a very strong warming of ca. 8°C over the last Termination and substantial millennial‐scale variability in the glacial section largely consistent with our planktonic foraminifera oxygen isotope (δ18O) record of Neogloboquadrina pachyderma (sin.). The timing and structure of the Termination and some of the millennial‐scale SST fluctuations are very similar to those observed in the well‐dated SST record from ODP Site 1233 (41°S) and the temperature record from Drowning Maud Land Antarctic ice core supporting the hemispheric‐wide Antarctic timing of SST changes. However, differences in our new SST record are also found including a long‐term warming trend over Marine Isotope Stage (MIS) 3 followed by a cooling toward the Last Glacial Maximum (LGM). We suggest that these differences reflect regional cooling related to the proximal location of the southern Patagonian Ice Sheet and related meltwater supply at least during the LGM consistent with the fact that no longer SST cooling trend is observed in ODP Site 1233 or any SST Chilean record. This proximal ice sheet location is documented by generally higher contents of ice rafted debris (IRD) and tetra‐unsaturated alkenones, and a slight trend toward lighter planktonic δ18O during late MIS 3 and MIS 2.

Here we present new surface water records from sediment core MD07‐3128 recovered at 53°S off the Pacific entrance of the Strait of Magellan. The alkenone‐derived sea surface temperature (SST) record reveals a very strong warming of ca. 8°C over the last Termination and substantial millennial‐scale variability in the glacial section largely consistent with our planktonic foraminifera oxygen isotope (δ18O) record of Neogloboquadrina pachyderma (sin.). The timing and structure of the Termination and some of the millennial‐scale SST fluctuations are very similar to those observed in the well‐dated SST record from ODP Site 1233 (41°S) and the temperature record from Drowning Maud Land Antarctic ice core supporting the hemispheric‐wide Antarctic timing of SST changes. However, differences in our new SST record are also found including a long‐term warming trend over Marine Isotope Stage (MIS) 3 followed by a cooling toward the Last Glacial Maximum (LGM). We suggest that these differences reflect regional cooling related to the proximal location of the southern Patagonian Ice Sheet and related meltwater supply at least during the LGM consistent with the fact that no longer SST cooling trend is observed in ODP Site 1233 or any SST Chilean record. This proximal ice sheet location is documented by generally higher contents of ice rafted debris (IRD) and tetra‐unsaturated alkenones, and a slight trend toward lighter planktonic δ18O during late MIS 3 and MIS 2.</p></abstract><abstract style="short"><p>Glacial millennial‐scale paleoceanographic changes in the southeast Pacific Antarctic timing and structure of SSTs and d18O very similar to ODP site 1233 Northward shift of Southern Ocean fronts and the opal belt during cold periods</p></abstract><textClass><keywords scheme="keyword"><list><head>keywords</head><item><term>Patagonian Ice Sheet</term></item><item><term>alkenones</term></item><item><term>ice rafted debris</term></item><item><term>millennial‐scale changes</term></item><item><term>southeast Pacific</term></item></list></keywords></textClass><textClass><keywords scheme="Journal Subject"><list><head>index-terms</head><item><term>BIOGEOSCIENCES</term></item><item><term>Paleoclimatology and paleoceanography</term></item><item><term>ATMOSPHERIC PROCESSES</term></item><item><term>Paleoclimatology</term></item><item><term>PALEOCEANOGRAPHY</term></item><item><term>Continental climate records</term></item><item><term>Glacial</term></item><item><term>Interhemispheric phasing</term></item><item><term>Sea surface temperature</term></item><item><term>Paleoceanography</term></item></list></keywords></textClass><textClass><keywords scheme="Journal Subject"><list><head>article-category</head><item><term>Regular Articles</term></item></list></keywords></textClass></profileDesc><revisionDesc><change when="2010-08-22">Received</change><change when="2011-06-20">Registration</change><change when="2011-09">Published</change></revisionDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/52CB573811162AAC46D1DD86D04C60F13A2F2F4A/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Wiley, elements deleted: body"><istex:xmlDeclaration>version="1.0" encoding="UTF-8" standalone="yes"</istex:xmlDeclaration><istex:document><component type="serialArticle" version="2.0" xml:lang="en" xml:id="palo1700"><header><publicationMeta level="product"><doi>10.1002/(ISSN)1944-9186</doi><issn type="print">0883-8305</issn><issn type="electronic">1944-9186</issn><idGroup><id type="product" value="PALO"></id><id type="coden" value="POCGEP"></id></idGroup><titleGroup><title type="main" xml:lang="en" sort="PALEOCEANOGRAPHY">Paleoceanography</title><title type="short">Paleoceanography</title></titleGroup></publicationMeta><publicationMeta level="part" position="30"><doi>10.1002/palo.v26.3</doi><numberingGroup><numbering type="journalVolume" number="26">26</numbering><numbering type="journalIssue">3</numbering></numberingGroup><coverDate startDate="2011-09">September 2011</coverDate></publicationMeta><publicationMeta level="unit" position="50" type="article" status="forIssue"><doi>10.1029/2010PA002049</doi><idGroup><id type="editorialOffice" value="2010PA002049"></id><id type="society" value="PA3221"></id><id type="unit" value="PALO1700"></id></idGroup><countGroup><count type="pageTotal" number="10"></count></countGroup><titleGroup><title type="articleCategory">Regular Articles</title><title type="tocHeading1">Regular Articles</title></titleGroup><copyright ownership="thirdParty">Copyright 2011 by the American Geophysical Union.</copyright><eventGroup><event type="manuscriptReceived" date="2010-08-22"></event><event type="manuscriptRevised" date="2011-06-11"></event><event type="manuscriptAccepted" date="2011-06-20"></event><event type="firstOnline" date="2011-09-15"></event><event type="publishedOnlineFinalForm" date="2011-09-15"></event><event type="xmlConverted" agent="SPi Global Converter:AGUv3.44_TO_WileyML3Gv1.0.3 version:1.1;

Here we present new surface water records from sediment core MD07‐3128 recovered at 53°S off the Pacific entrance of the Strait of Magellan. The alkenone‐derived sea surface temperature (SST) record reveals a very strong warming of ca. 8°C over the last Termination and substantial millennial‐scale variability in the glacial section largely consistent with our planktonic foraminifera oxygen isotope (δ18O) record of Neogloboquadrina pachyderma (sin.). The timing and structure of the Termination and some of the millennial‐scale SST fluctuations are very similar to those observed in the well‐dated SST record from ODP Site 1233 (41°S) and the temperature record from Drowning Maud Land Antarctic ice core supporting the hemispheric‐wide Antarctic timing of SST changes. However, differences in our new SST record are also found including a long‐term warming trend over Marine Isotope Stage (MIS) 3 followed by a cooling toward the Last Glacial Maximum (LGM). We suggest that these differences reflect regional cooling related to the proximal location of the southern Patagonian Ice Sheet and related meltwater supply at least during the LGM consistent with the fact that no longer SST cooling trend is observed in ODP Site 1233 or any SST Chilean record. This proximal ice sheet location is documented by generally higher contents of ice rafted debris (IRD) and tetra‐unsaturated alkenones, and a slight trend toward lighter planktonic δ18O during late MIS 3 and MIS 2.</abstract><abstract type="short">Glacial millennial‐scale paleoceanographic changes in the southeast Pacific Antarctic timing and structure of SSTs and d18O very similar to ODP site 1233 Northward shift of Southern Ocean fronts and the opal belt during cold periods</abstract><note type="additional physical form">Tab‐delimited Table 1.</note><subject><genre>keywords</genre><topic>Patagonian Ice Sheet</topic><topic>alkenones</topic><topic>ice rafted debris</topic><topic>millennial‐scale changes</topic><topic>southeast Pacific</topic></subject><relatedItem type="host"><titleInfo><title>Paleoceanography</title></titleInfo><titleInfo type="abbreviated"><title>Paleoceanography</title></titleInfo><genre type="journal">journal</genre><subject><genre>index-terms</genre><topic authorityURI="http://psi.agu.org/taxonomy5/0400">BIOGEOSCIENCES</topic><topic authorityURI="http://psi.agu.org/taxonomy5/0473">Paleoclimatology and paleoceanography</topic><topic authorityURI="http://psi.agu.org/taxonomy5/3300">ATMOSPHERIC PROCESSES</topic><topic authorityURI="http://psi.agu.org/taxonomy5/3344">Paleoclimatology</topic><topic authorityURI="http://psi.agu.org/taxonomy5/4900">PALEOCEANOGRAPHY</topic><topic authorityURI="http://psi.agu.org/taxonomy5/4914">Continental climate records</topic><topic authorityURI="http://psi.agu.org/taxonomy5/4926">Glacial</topic><topic authorityURI="http://psi.agu.org/taxonomy5/4938">Interhemispheric phasing</topic><topic authorityURI="http://psi.agu.org/taxonomy5/4954">Sea surface temperature</topic><topic authorityURI="http://psi.agu.org/taxonomy5/4900">Paleoceanography</topic></subject><subject><genre>article-category</genre><topic>Regular Articles</topic></subject><identifier type="ISSN">0883-8305</identifier><identifier type="eISSN">1944-9186</identifier><identifier type="DOI">10.1002/(ISSN)1944-9186</identifier><identifier type="CODEN">POCGEP</identifier><identifier type="PublisherID">PALO</identifier><part><date>2011</date><detail type="volume"><caption>vol.</caption><number>26</number></detail><detail type="issue"><caption>no.</caption><number>3</number></detail><extent unit="pages"><start>n/a</start><end>n/a</end><total>10</total></extent></part></relatedItem><identifier type="istex">52CB573811162AAC46D1DD86D04C60F13A2F2F4A</identifier><identifier type="DOI">10.1029/2010PA002049</identifier><identifier type="ArticleID">2010PA002049</identifier><accessCondition type="use and reproduction" contentType="copyright">Copyright 2011 by the American Geophysical Union.</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
