attribute	NC_GLOBAL	acquisition_description	String	Sediment core PTLN\u2010PC1 was collected September 2013 in sequential 1\u2010m sections using a 5\u2010cm\u2010diameter Colinvaux\u2010Vohnout Livingstone\u2010type rod\u2010operated piston corer (Geocore, Columbus, Ohio). Each section was sealed in the field and refrigerated at 4 \u00b0C until core splitting and subsampling. Thirteen macrofossils were pulled from the core and were pretreated with an acid\u2010base\u2010acid procedure according to the protocol in Brock et al. (2010) to remove extraneous organic materials. Accelerator mass spectrometry 14C dating was performed by DirectAMS in Bothell, WA, United States.

attribute	NC_GLOBAL	instruments_0_dataset_instrument_nid	String	771668
attribute	NC_GLOBAL	instruments_0_description	String	The piston corer is a type of bottom sediment sampling device. A long, heavy tube is plunged into the seafloor to extract samples of mud sediment. A piston corer uses a "free fall" of the coring rig to achieve a greater initial force on impact than gravity coring. A sliding piston inside the core barrel reduces inside wall friction with the sediment and helps to evacuate displaced water from the top of the corer. A piston corer is capable of extracting core samples up to 90 feet in length.

attribute	NC_GLOBAL	instruments_1_description	String	An AMS measures "long-lived radionuclides that occur naturally in our environment. AMS uses a particle accelerator in conjunction with ion sources, large magnets, and detectors to separate out interferences and count single atoms in the presence of 1x1015 (a thousand million million) stable atoms, measuring the mass-to-charge ratio of the products of sample molecule disassociation, atom ionization and ion acceleration." AMS permits ultra low-level measurement of compound concentrations and isotope ratios that traditional alpha-spectrometry cannot provide.

attribute	NC_GLOBAL	projects_0_description	String	This project will survey the taxonomic, genetic, and functional diversity of the organisms found in marine lakes, and investigate the processes that cause gains and losses in this biodiversity. Marine lakes formed as melting ice sheets raised sea level after the last glacial maximum and flooded hundreds of inland valleys around the world. Inoculated with marine life from the surrounding sea and then isolated to varying degrees for the next 6,000 to 15,000 years, these marine lakes provide multiple, independent examples of how environments and interactions between species can drive extinction and speciation. Researchers will survey the microbes, algae, invertebrates, and fishes present in 40 marine lakes in Palau and Papua, and study how diversity has changed over time by retrieving the remains of organisms preserved in sediments on the lake bottoms. The project will test whether the number of species, the diversity of functional roles played by organisms, and the genetic diversity within species increase and decrease in parallel; whether certain species can greatly curtail diversity by changing the environment; whether the size of a lake determines its biodiversity; and whether the processes that control diversity in marine organisms are similar to those that operate on land. Because biodiversity underlies the ecosystem services on which society depends, society has a great interest in understanding the processes that generate and retain biodiversity in nature. This project will also help conserve areas of economic importance. Marine lakes in the study region are important for tourism, and researchers will work closely with governmental and non-governmental conservation and education groups and with diving and tourism businesses to raise awareness of the value and threats to marine lakes in Indonesia and Palau.
