Limnological and nearshore diatom communities of Heard Island: proxies of subantarctic climate change?
Entry ID: ASAC_2396

Abstract: ---- Public Summary from Project ----
Heard Island offers scientists a unique subantarctic laboratory for investigating climate change. We will establish a reference set of microalgal floras from lakes and lagoons and ultimately use the microalgal floras of today to investigate changes in fossil microalgal communities of Heard Island lake and lagoonal ecosystems to better understand regional subantarctic climate changes.

Sediments were sampled with hand corers.
Water samples were collected with a Niskin bottle.

The dataset contains a summary of the locations data were sampled from, as well as average isotope concentrations from each sampling location.
