9.15 am to 5.45 pm
Boat trip
We are delighted to welcome Prof Jed Kaplan again to lead a boat geological and geomorphological excursion to the beautiful and inaccessible northeastern coast and islands of Hong Kong.

The boat travels along the Tolo Channel, a flooded river valley that follows the major extinct fault line that bisects Hong Kong.  It then passes the rocky shore of Lai Chi Chong, and conditions permitting, we shall dock and explore the Jurassic sedimentary and volcanic rocks along a wave-cut platform.  The boat then sails to Chek Chau (Port Island) where we circumnavigate the island.  Here, we view dipping sedimentary rocks that were originally formed in a desert setting.  The boat then visits Bluff Head where the territory’s oldest – at 360 million years – rocks are exposed in a vertical dipping succession. 

The boat then sails to the western end of Double Island to view supratidal platforms and the Yan Chau Tong Marine Park.  Passing through Double Haven, we see the “Sombrero Islands”, before docking at the highlight of Ap Chau, a sedimentary island made up of angular rocks.  Importantly, the island is the location of Hong Kong's largest natural sea arch which we shall walk through and over. 

The excursion then passes by Kat O to view its steep rugged coastline and sea caves and by Governor's Beach on Double Island, a stunning cove reserved for the Governor's Yacht until the 1970s where swimming should be possible.

Throughout the boat trip, Prof Kaplan introduces the geology of the surrounding areas with a sumptuous professionally catered lunch.

Prof Jed Kaplan studied Geography and Earth Sciences at Dartmouth College, USA, and received his PhD in Plant Ecology from Lund University, Sweden.  He subsequently held several postdoctoral fellowships.  Later, he held Professorships at the Universities of Geneva and Lausanne, Switzerland, supported by the European Research Council.  Prof Kaplan was a Senior Research Fellow in the Environmental Change Institute, University of Oxford, and is currently Associate Professor in the Department of Earth Sciences, University of Hong Kong.  He has published more than 100 articles in major international journals including Science and Nature, and is recognised as an expert in interdisciplinary global environmental history.  He is currently editor-in-chief of the journal Global and Planetary Change.
