Supporting data for “Impacts of Pliocene-Pleistocene global climatic events on tropical deep-sea biota: Investigation based on IODP Expedition 363 Western Pacific Warm Pool”

Main idea of the research project:

In summary, we take advantage of microfossil ostracodes and use them to investigate:

1. Deep-sea ostracode assemblage in the WPWP (IAA biodiversity hotspot).

2. The impact of the ITF restriction on the deep-sea ecosystem in the equatorial Indian Ocean.

3. The biotic response of ostracodes to the epicontinental sea-shallow marine shift of the river mouth region of the Sepik River of Papua New Guinea in the Pleistocene.

4. The biotic response of deep-sea ostracodes to the alternation of the dominated water mass in the deep equatorial Pacific Ocean at the Pliocene-Pleistocene boundary.

The results of this project will help us better understand the relationship between climate and marine ecosystems in the world biodiversity center.

Detailed description on the data:

The core sample collected from the IODP 363 Western Pacific Warm Pool were processed in the lab. we picked out, sorted and identified the ostracode microfossil from the sediments. We compute the total abundance and relative abundance of each genus of ostracode. This file includes these total/relative abundance data, also the core depth and age data for the plottug and statical analysis. This dataset is used to create the total/ relative abundance against water depth plots and the NMDS analysis in my Mphil thesis.
