C14 and N15 isotopes in rocks and animals from methane seep hard substrate ecosystems Dataset Description: <p>Average stable isotopic signatures (d15N and d13C) for carbonate rocks and animals collected during AT 15-44 at various methane seep sites on the Costa Rica margin. The values are averages, not actual measurements.&nbsp; Researchers needing the raw data should seek them from llevin@ucsd.edu.</p>

<p>From Final Report:</p>
<p>At Costa Rica, carbonate organic matter content was high (0.5 to 3.5%).&nbsp; Organic matter in the carbonates had d 13C signatures of -65o/oo to -23o/oo indicating a varied methane contribution to the C pool. Faunal isotopic signatures ranged broadly, from -101o/oo to -10o/oo for d13C and -12 to +18 for d 15N.&nbsp;&nbsp; They revealed strong trophic resource partitioning among mollusk and polychaete species. A broad range of d 13C&nbsp; signatures reflect use of a variety of microbial food resources, often within a single rock.&nbsp; Very light d 13C signatures (mean -92o/oo, n=18) in an abundant dorvilleid polychaete (Dorvillea sp.) in the most sulfidic carbonates provides evidence of a carbonate endolithofauna that may rely primarily on archaeal carbon. Intense grazing of rocks by lepetopsid limpets&nbsp; many with isotopic evidence for methane-derived C, apparently exerts strong top-down control on the distribution of protists and smaller invertebrates.<br />
<br />
At Hydrate Ridge, inorganic d13C values of carbonates ranged from -26o/oo to -54o/oo, whereas the rock organic d13C spanned a much broader range (from -19o/oo to -71o/oo.).&nbsp; Within a rock the two values were not correlated and there were no significant isotopic differences on average between active and inactive carbonates, although inactive values were less variable.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Natural abundance animal carbon isotope signatures ranged from -17o/oo to -88o/oo, with average values of animals (per rock) showing no significant difference between active and inactive sites (P-0.232). However, carbonate d13C org (P=0.002) and d15N (animal P=0.005) were isotopically lighter on rocks designated as active, relative to those designated as inactive.<br />

Short-term colonization processes at Costa Rica methane seeps

Short-term colonization processes at Costa Rica methane seeps
<p>This RAPID project will conduct 5 submersible or ROV dives to collect a series of colonization experiments deployed in March 2009 on Mound 12 off Costa Rica (997 m). These experiments were deployed opportunistically, and to optimize the information that could be obtained, the PIs needed to recover them within a 12 month time frame. Early colonization of rock, wood, shell and tube substrates will be studied. The microbes, foraminiferans and metazoans present after 6-12 mo will be compared to those colonizing similar experiments to be deployed at Hydrate Ridge, where seeps occur within an oxygen minimum zone. The overall project goal is to integrate physical, geological, chemical and biological data to develop a holistic view of the influence of seep-generated carbonate hard-ground ecosystems on margins.</p>
<p>The objectives of the research are to (a) Compare colonizers at seeps off Costa Rica and Hydrate Ridge to assess the importance of different oxygen regimes in the development of anaerobic methane oxidation, sulfide oxiders and other microbial metabolisms on hard substrates, and to evaluate their roles in driving protozoan and metazoan succession at methane seeps. (b) Deploy a suite of biotic and abiotic substrates to distinguish the specific roles of carbonate substrate from those of other hard substrates (wood, clam and mussel shells, worm tubes) available. (c) Explore the similarity of vent and seep colonization processes by comparing colonization at the Costa Rica seeps, where vent species are common, to the Hydrate Ridge seeps, where they are not. (d) Determine whether there are diagnosable biogeographic isotope or other biomarker signatures from newly recruited Costa Rica microbial, foraminiferal and animal populations at active vs. inactive seeps, and whether these differ from those at Hydrate Ridge.</p>
<p>This research will involve international participation from Costa Rican scientists at the Univ. of Costa Rica. </p>

<p>Samples were kept cold (5o C), sieved through a 0.3 mm mesh, and sorted live at sea to collect macrofauna for stable isotopic analyses. Living specimens were identified, allowed to clear guts overnight in filtered seawater, washed in milli Q water and placed in preweighed tin boats or combusted vials (500o C overnight) and frozen at 70o C. In the laboratory, specimens were oven dried (60o C), weighed and acidified with 1% PtCl2 to remove inorganic C. Stable isotope measurements (d13C, d15N) were made on single individuals, parts of individuals or several small specimens of a single species combined. Analyses were conducted on a Finnigan Conflow 2 continuous flow system and a Fisons NA 1500 elemental analyzer coupled to a Finnegan Delta S isotope ratio mass spectrometer at Boston University and on a continuous flow PDZ Europa 20/20 isotope ratio mass spectrometer at UC Davis. Isotope ratios are expressed as d13C or d15N in units of per mil (o/oo). Standards were Pee Dee Belemnite Belemnite and nitrogen gas (atmospheric). Estimates of the percentage of methane-derived carbon in the macrofaunal carbon pool of each region and habitat were generated using a two-source, single isotope mixing model as in Fry &amp; Sherr (1984). The formula is:<br />
Fm = (di - dPOC)/(dm - dPOC)<br />
where di, dPOC, and dm refer to the d13C signatures of infauna, particulate organic carbon (POC), and methane, respectively. The POC value was taken to be the average d13C signature of non-seep fauna sampled by this study in each region. No trophic shift was included as this is negligible (&lt;1o/oo per trophic level) for d13C.</p>
