“…In ascending order, the recorded dinoflagellate cyst events are: the HO of Emmetrocysta urnaformis, the HO and HCO of Hystrichokolpoma rigaudiae, the HO of Cannosphaeropsis quattrocchiae, the HO of Cousteaudinium auybriae, the HO of Cleistosphaeridium ancyreum, the HO of Labyrinthodinium truncatum, the HO of Operculodinium piaseckii, and the HO of Reticulatosphaera actinocoronata. The ranges of these selected taxa are discussed and compared with the previously published ranges according to Bijl (2022) and with the most recent well-documented information on Neogene dinoflagellate cysts recorded from various sites across the North and South Atlantic Ocean and adjacent seas (e.g. Poulsen et al 1996;Stover et al 1996;Channell et al 1999a;Jim enez Moreno et al 2006;De Schepper and Head 2008;Dybkjaer and Piasecki 2010;Schreck et al 2012;De Schepper et al 2015, 2017King 2016;Boyd et al 2018;Pinz on et al 2022).…”

The present work documents the stratigraphic distribution of dinoflagellate cysts from the upper part (60-585 m) of the YPF.Ch. PV. es-1 borehole, Pen ınsula Vald es, Argentina. The assemblages exhibit a relatively moderate to low diversity. Most samples are characterized by frequent to abundant taxa of the order Gonyaulacales, such as Spiniferites/Achomosphaera spp., Reticulatosphaera actinocoronata, Operculodinium centrocarpum, and Melitasphaeridium choanophorum. Furthermore, a continuous succession of Early Miocene-Late Miocene diagnostic dinoflagellate cyst events was recorded for the first time from the Pen ınsula Vald es region. Eight diagnostic events of highest occurrences (HOs) of dinoflagellate cyst taxa are identified. These bioevents allowed a subdivision of the sedimentary succession into two well-defined stratigraphic sections: Early to Middle Miocene (Burdigalian-Langhian/probably Serravalian, 430/425-330/325 m) based on the HOs of Emmetrocysta urnaformis, Cannosphaeropsis quattrocchiae, Cousteaudinium auybriae, and Cleistosphaeridium ancyreum, and Late Miocene (Tortonian-Messinian, between 175-170 and 80/85 m) based on the HOs of Labyrinthodinium truncatum subsp. truncatum, Operculodinium piaseckii, and Reticulatosphaera actinocoronata. The ranges of these taxa are compared with well-documented information on Neogene dinoflagellate cysts recorded from different sites across the North and South Atlantic Ocean and adjacent seas. In general, the dinoflagellate cyst assemblages, as well as the selected diagnostic taxa, exhibit a clear similarity to those of the Northern Hemisphere. The only exception is Hystrichokolpoma rigaudiae, which is asynchronous, possibly indicating local paleoenvironmental conditions.

“…It is therefore important to compare shipboard generated data with the large body of previous dinocyst work from the North Atlantic region, including the Norwegian Margin, and palynological studies using core material from earlier expeditions to the Vøring Plateau (e.g., Boulter and Manum, 1989;Mudie, 1989;Eldrett et al, 2004). Here, we employ the latest global and regional compilations (Bijl, 2022), wherein dinocyst events are calibrated against the GTS2012.…”

publications.iodp.org • 3 known because of the deviation of the pipe below the ship, which can vary depending on water currents, tides, and water depth; the hole position is thus known typically within 10 m accuracy.Drilling sites were numbered according to the series that began with the first site drilled by the D/V Glomar Challenger in 1968. Starting with Integrated Ocean Drilling Program Expedition 301, the prefix "U" designates sites occupied by JOIDES Resolution. When drilling multiple holes at a site, hole locations are typically offset from each other by ~20 m. During Expedition 396, we offset holes at an average of 115 m, except for Site U1570, where holes were offset as far as 1772 m. Site U1570 was approved by EPSP as a 2 km long "ribbon" or transect west of Site U1569 with start and end coordinates. This ribbon provided an alternate coring strategy to Site U1569, where deep stratigraphic targets were outcropping at shallower subseafloor depths. A letter suffix distinguishes each hole drilled at the same site. The first hole drilled is assigned the site number modified by the suffix "A," the second hole takes the site number and the suffix "B," and so forth. During Expedition 396, 21 holes were drilled at 10 sites (U1565-U1574; see Figure F4 in the Expedition 396 summary chapter [Planke et al., 2023a]).
