One-Year Ago (06-January-2016) — Pacific Ocean

Day 2 of 102. Semester at Sea, Spring 2016 Voyage. Crossing the Pacific Ocean from Mexico to Hawaii.

This was our first full day at sea. I woke at 05:30. Both the moon and Venus were visible before sunrise. The seas were calmer than during the night. I was not impacted, but I know some of the folks were sea-sick. Like my previous Semester at Sea voyages (six Enrichment, two Semester), I made it a goal to take pictures at dawn, sunrise, sunset, and dusk on as many days as possible. It did mean missing a lot of sleep, but there is something special about sunrise and sunset at sea. I hope you enjoy some of these images over the next 100+ days. The first day at sea was mainly orientation sessions, and time for those that have not been to sea before to get used to the motion on the ship. Classes started on the next day. Latter in the afternoon while walking around the ship, I found one of the students working on watercolor painting in the late afternoon sun.
