anonymous 16352 Carbon, nitrogen and stable carbon isotopes, and radionuclides in sediment cores from Segara Anakan Lagoon, Berau and Kongsi Island, Indonesia, 2013 and 2016 This compilation contains data from 18 mangrove sediment cores: organic carbon (Corg), total nitrogen (N) and stable carbon isotope composition (δ13Corg). For 3 cores, gamma emitting radionuclides data are additionally available. The cores were sampled in Segara Anakan Lagoon (Central Java), Berau (East Kalimantan) and Kongsi Island (Thousand Islands Marine National Park, Jakarta), in Indonesia. Sediment samples from Segara Anakan Lagoon and Kongsi Island were taken in October - December 2016. Sediment samples from Berau were taken in May 2013. The mangrove sediment cores were collected using a 1 m long semi-cylindrical auger. Sediments were taken down to 1 m depth, and were sampled in 5 cm intervals. 16360 https://doi.org/10.1594/PANGAEA.896852 2018-12-19T13:47:38+0000 2018 14151 18584 18583 18582 18581 18580 18675 18608 18617 18604 18671 18673 18615 18680 18600 18621 18602 18677 18586 18610 18579 18613 18606 18669 18240 18611 18676 18609 18618 18605 18672 18674 18616 18681 18601 18622 18603 18678 18587 18585 18614 18607 18670 16375 16470 Kusumaningtyas, Mariska Astrid; Hutahaean, Andreas A; Fischer, Helmut W; Pérez-Mayo, Manuel; Ransby, Daniela; Jennerjahn, Tim C (2018): Carbon, nitrogen and stable carbon isotopes, and radionuclides in sediment cores from Segara Anakan Lagoon, Berau and Kongsi Island, Indonesia, 2013 and 2016 [dataset publication series].
