In fall 1992 and spring 1993 we drilled an unusual big colony of Porites sp. at the fore-reef at Aqaba. The colony is situated in front of the reef edge of the fringing reef south of the Marine Science Station. The colony grows from a depth of ca 4.5 m, reaches a height of 3.5 m and a maximum diameter of approximately 5.5 m. We drilled with a hand held pneumatic drill powered by compressed air from a Scuba tank. We used a conventional 30cm diamond-tipped drill bit and in order to obtain longer cores we constructed extensions of 100cm each (3 in total). The extensions are made from a 17mm diameter steel rod with a screw thread attached either to the core barrel or another extension. Up to 320 cm long cores in 30cm lengths with 100% recovery were obtained. The core holes were filled with cement plugs after drilling to prevent bioerosion (see Hudson 1981; Winter et al. 1991) . The cores were drilled parallel to the growth axis (perpendicular to the coral surface). Five cores were extracted from the "big" Porites sp. at different sides of the colony. Three cores (19, 20, 21) are of 130 cm length, core 24 (lying SE-side of the colony at an angle of 45deg) reached 229 cm length, and core 18 (top of the colony) recovered coral skeleton to a total length of 312 cm. For oxygen and carbon isotope analysis core 18 (top of colony) and core 19 (horizontal core from the southern side) were selected. Samples for isotopic analyses were treated with 35% hydrogen peroxide for 24 hours to remove oxidizable organic material. In addition they were rinsed several times in demineralized water and dried in a stove at 40 degC. Small samples to determine the average isotope composition of each year were cut with a hand held saw. They were taken along the edge of the coral slabs. The top of LD-bands was chosen as the end (respectively beginning) of an annual band. In all our samples this boundary is sharp and can be determined relatively precisely. Each chip was gently powdered in an agate mortar. The samples were reacted with 100% H3PO4 at 75 degC in an online, automated carbonate reaction device (Kiel Device) connected to a Finnigan Mat 252 mass spectrometer. Isotopic ratios were corrected for 17-O contribution (Craig 1957) and are reported in permil relative to PDB. Average precision based on duplicate sample analysis and on multiple analysis of NBS 19 is +/- 0.04 permil for d13C and +/- 0.08 permil for d18O. #-------------------- # Publication # Authors: Heiss, G.

We describe additions to a collection prepared for use in paleoclimate state estimation, specifically the Last Millennium Reanalysis (LMR). The 2290 additional series include 2152 tree ring chronologies and 138 other series. They supplement the collection used previously and together form a database titled LMRdb 1.0.0. The additional data draws from lake core, ice core, coral, speleothem, and tree ring archives, using published data primarily from the NOAA Paleoclimatology archive and a set of tree ring width chronologies standardized from raw International Tree Ring Data Bank ring width series. In contrast to many previous paleo compilations, the data were not selected (screened) on the basis of their environmental correlation, multi-century length, or other attributes. The inclusion of proxies sensitive to moisture and other environmental variables expands their use in data assimilation. A preliminary calibration using linear regression with mean annual temperature reveals characteristics of the proxy series and their relationship to temperature, as well as the noise and error characteristics of the records. The additional records are structured as individual files in the NOAA Paleoclimatology format and archived at NOAA Paleoclimatology (Anderson et al. 2018) and will continue to be improved and expanded as part of the LMR Project. The additions represent a four-fold increase in the number of records available for assimilation, provide expanded geographic coverage, and add additional proxy variables. Applications include data assimilation, proxy system model development, and paleoclimate reconstruction using climate field reconstruction and other methods. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Funding_Agency_Name: National Science Foundation # Grant:AGS-1304263 # Funding_Agency_Name: National Oceanic and Atmospheric Administration # Grant:NA14OAR4310176 #------------------ # Site_Information # Site_Name: Gulf of Aqaba, Red Sea, Jordan # Location: Ocean>Indian Ocean>Red Sea # Country: Jordan # Northernmost_Latitude: 29.42 # Southernmost_Latitude: 29.42 # Easternmost_Longitude: 34.97 # Westernmost_Longitude: 34.97 # Elevation: -4.5 m #------------------ # Data_Collection # Collection_Name: 94reds02a # Earliest_Year: 1886 # Most_Recent_Year: 1992 # Time_Unit: y_ad # Core_Length: 1.2 m # Notes: {"database":"LMR"} Core name- aq19.
