Ocean acidification and increased temperature have both positive and negative effects on early ontogenetic traits of a rocky shore keystone predator species

Patricio H Manríquez, María Elisa Jara, Mylene E Seguel, Rodrigo Torres, Emilio Alarcon, Matthew R Lee & H G Dam
The combined effect of ocean acidification and warming is expected to have significant effects on several traits of marine organisms. The gastropod Concholepas concholepas is a rocky shore keystone predator characteristic of the south-eastern Pacific coast of South America and an important natural resource exploited by small-scale artisanal fishermen along the coast of Chile and Peru. In this study, we used small juveniles of C. concholepas collected from the rocky intertidal habitats of southern Chile...

Slow shell building, a possible trait for resistance to the effects of acute ocean acidification, supplement to: Waldbusser, George G; Gray, Matthew W; Hales, Burke; Langdon, Chris; Haley, Brian A; Gimenez, Iria; Smith, Stephanie R; Brunner, Elizabeth L; Hutchinson, Greg (2016): Slow shell building, a possible trait for resistance to the effects of acute ocean acidification. Limnology and Oceanography, 61(6), 1969-1983

Increasing anthropogenic carbon dioxide is altering marine carbonate chemistry through a process called ocean acidification. Many calcium carbonate forming organisms are sensitive to changes in marine carbonate chemistry, especially mollusk bivalve larvae at the initial shell building stage. Rapid calcification, limited energy reserves, and more exposed calcification surfaces, are traits at this stage that increase vulnerability to ocean acidification through our previously argued kinetic-energetic hypothesis. These developmental traits are common to broadcast spawning bivalve species...

Analysis of manganese nodules from Lake Baikal, supplement to: Bukharov, A A; Murashko, D N; Fialkov, V A (1993): Ferromanganese nodules on the underwater slopes of the Uskahan Islands, Lake Baykal. International Geology Review, 35(1), 89-100

A A Bukharov, D N Murashko & V A Fialkov
Although ferromanganese crusts from shallow depths in Lake Baykal have been described previously, the presence of nodules at depths of about 500 m are a new discovery made possible by exploration using manned submersibles. The nodules are comparable to oceanic nodules in composition, but have some significant differences, including a more rapid rate of growth. Sedimentary-diagenetic processes are mainly responsible for their formation, but there is reason to believe hydrothermal fluids play some role.

Annotated record of the detailed examination of Mn deposits from DSDP Leg 33 (Holes 314, 315A, 317A, 318), supplement to: Jenkyns, Hugh C (1976): Sediments and Sedimentary History, Manihiki Plateau, South Pacific Ocean. In: Schlanger, S.O.; Jackson, E.D.; et al., Initial Reports of the Deep Sea Drilling Project, U.S. Government Printing Office, XXXIII, 873-890

Hugh C Jenkyns
The Manihiki Plateau is an elevated area of shallow oceanic crust in the South Pacific; it was formed during Early Cretaceous time by profuse outpourings of basalt. DSDP Holes 317, 317A, and 317B, on which this account is based, are situated in a basinal area on the so called High Plateau, the shallowest part of the volcanic edifice, where depths range between 2000 and 3000 meters. The oldest sediments cored are Lower Cretaceous greenish-black volcaniclastics...

Stable isotope data (δ¹³C) from sediment core SO201-2-101KL (58°52' N, 170°41' E) and ODP Site 1240 (00°01' N, 82°27' W), supplement to: Max, Lars; Rippert, Nadine; Lembke-Jene, Lester; Mackensen, Andreas; Nürnberg, Dirk; Tiedemann, Ralf (2016): Evidence for enhanced convection of North Pacific Intermediate Water to the low-latitude Pacific under glacial conditions.

We provide high-resolution foraminiferal stable carbon isotope (d13C) records from the subarctic Pacific and Eastern Equatorial Pacific (EEP) to investigate circulation dynamics between the extra-tropical and tropical North Pacific during the past 60 kyr. We measured the d13C composition of the epibenthic foraminiferal species Cibicides lobatulus from a shallow sediment core recovered from the western Bering Sea (SO201-2-101KL; 58°52.52' N, 170°41.45' E; 630 m water depth) to reconstruct past ventilation changes close to the source...

Annotated record of the detailed examination of Mn deposits from the 7TOW cruise among the Line Islands Guyots in the Pacific Ocean, supplement to: Natland, James H (1976): Petrology of Volcanic Rocks Dredged from Seamounts in the Line Islands. In: Schlanger, S.O.; Jackson, E.D.; et al., Initial Reports of the Deep Sea Drilling Project, U.S. Government Printing Office, XXXIII, 749-777

James H Natland
Volcanic rocks dredged from the tops of seamounts in the Line Islands and cored from their flanks demonstrate that this is a region of extreme petrologic diversity. Tholeiitic and alkalic basalts were obtained in a single dredge haul and a wide spectrum of alkalic differentiates, including quartz trachytes, and phonolites were dredged or cored elsewhere. Four dredge stations on widely scattered seamounts recovered potassic nephelinites, unlike any other volcanic rocks heretofore found in the ocean...

Downward spectral solar irradiance as measured in different depths under sea ice (transmitted irradiance) at ROV station PS81/566-1

Klaus M Meiners & Stefanie Arndt
Measurements of solar radiation over and under sea ice have were carried out during the expedition ANT-29/7 of the German ice-breaker R/V Polarstern during the 'Winter studies on sea ice and key species' (WISKEY) project in the northern Weddell Sea. The given data were collected during the second ice camp from 18 to 26 September 2013 on a 100m-by-100m grid during 17 dives of the Remotely Operated Vehicle (ROV). All radiation measurements have been performed...

Influence of snow depth and surface flooding on light transmission through Antarctic pack ice, supplementary data, supplement to: Arndt, Stefanie; Meiners, Klaus M; Ricker, Robert; Krumpen, Thomas; Katlein, Christian; Nicolaus, Marcel (2017): Influence of snow depth and surface flooding on light transmission through Antarctic pack ice. Journal of Geophysical Research: Oceans, 122(3), 2108-2119

Stefanie Arndt, Klaus M Meiners, Robert Ricker, Thomas Krumpen, Christian Katlein & Marcel Nicolaus
Snow on sea ice alters the properties of the underlying ice cover as well as associated physical and biological processes at the interfaces between atmosphere, sea ice, and ocean. The Antarctic snow cover persists during most of the year and contributes significantly to the sea-ice mass due to the widespread surface flooding and related snow-ice formation. Snow also enhances the sea-ice surface reflectivity of incoming shortwave radiation and determines therefore the amount of light being...

The northwestern Pacific Ocean is the largest expanse of old oceanic lithosphere, and so the principal theme of Leg 32 set by the Pacific Advisory Panel was the late Mesozoic history of the Pacific Ocean. The main scientific goals originally set for the leg were to: 1) Determine the development of the very deep sea floor of the western Pacific, including the nature of its basement rocks and the age, lithology, and fossil content of...
