	abstract = {High-resolution bathymetric surveys from autonomous underwater vehicles ABE and D. Allan B. were merged to create a coregistered map of 71.7 km(2) of the Endeavour Segment of the Juan de Fuca Ridge. Radiocarbon dating of foraminifera in cores from three dives of remotely operated vehicle Doc Ricketts provide minimum eruption ages for 40 lava flows that are combined with the bathymetric data to outline the eruptive and tectonic history. The ages range from Modern to 10,700 marine-calibrated years before present (yr BP). During a robust magmatic phase from {\textgreater}10,700 yr BP to approximate to 4300 yr BP, flows erupted from an axial high and many flowed {\textgreater}5 km down the flanks; some partly buried adjacent valleys. Axial magma chambers (AMCs) may have been wider than today to supply dike intrusions over a 2 km wide axial zone. Summit Seamount formed by approximate to 4770 yr BP and was subsequently dismembered during a period of extension with little volcanism starting approximate to 4300 yr BP. This tectonic phase with only rare volcanic eruptions lasted until approximate to 2300 yr BP and may have resulted in near-solidification of the AMCs. The axial graben formed by crustal extension during this period of low magmatic activity. Infrequent eruptions occurred on the flanks between 2620-1760 yr BP and within the axial graben since approximate to 1750 yr BP. This most recent phase of limited volcanic and intense hydrothermal activity that began approximate to 2300 yr BP defines a hydrothermal phase of ridge development that coincides with the present-day 1 km wide AMCs and overlying hydrothermal vent fields.},

	abstract = {Inhabiting areas of the ocean where paleoenvironmental records are sparse, deep-sea corals represent valuable yet largely untapped Holocene records of intermediate and deep ocean variability. $δ$18O and $δ$13C were analyzed in nine live-collected deep-sea gorgonian corals (Isididae and Coralliidae) in order to further develop the {\textquotedblleft}lines{\textquotedblright} paleotemperature method. Least squares linear regression analysis for full lifespan $δ$18O vs. $δ$13C (corrected for $δ$18Owater and $δ$13CDIC) was utilized to yield equations of the form y = mx + b. $δ$18O and intercept values were found to be a function of temperature, and to approximate calcite $δ$18O equilibrium. The corals in this study extend the previously reported calibration (Hill et al., 2011) over a broader range of temperatures from 5 {\textdegree}C to 11.2 {\textdegree}C. When combined with the data from Hill et al. (2011), a new expression for the relationship between the $δ$18Ointercept value and temperature is proposed: T ({\textdegree}C) = -4.12 {\textpm} 0.38 ($δ$18Ointercept) + 12.32 {\textpm} 0.75(R2 = 0.90, p value {\textless} 0.0001) Error estimates are {\textpm} 0.7 {\textdegree}C for corals living at cold temperatures (2 {\textdegree}C), {\textpm} 1.4 {\textdegree}C in warmer waters (11 {\textdegree}C), and {\textpm} 0.5 {\textdegree}C at the mean water temperature of the data set (4.6 {\textdegree}C). The first multi-specimen verification of the {\textquotedblleft}lines{\textquotedblright} method was performed on three co-located bamboo (Isididae) corals and found to give nearly coincident $δ$18O intercepts. Detailed intraspecimen sampling reveals $δ$18O and $δ$13C isotopic variability within coeval portions of the skeleton. In one specimen, {\textquotedblleft}lines{\textquotedblright} method analysis was utilized on multiple samples taken from the same temporal increment of the skeleton, yielding multiple $δ$18O intercepts. Calculated temperatures using the calibration proposed here describe a temperature range of 7.9 to 10.3 {\textdegree}C, which approaches the temperature range of 11.1 {\textpm} 0.7 {\textdegree}C at the coral collection location.},
