On my fourth birthday,my father found me at the bottom of the pool,sharing air supply,or"buddy breath-
ing",with a family friend;I was having my first scuba experience.I've been diving ever since,and on expedi-
tions to some of the most remote parts of the globe,since age 7.As an adult,I've led teams to dive with orcas
and great white sharks,to the North Pole and to the bottom of the Mediterranean Sea,and to live underwater
for 31 days.The journey has been full of gratifying experiences as well as challenges-some of them painful.
My grandfather was a pioneer of ocean exploration.He contributed to the invention of many of the tools
he needed-scuba,underwater cameras and more-because he saw the need for innovation to learn and ex-
plore.He would frequently cite a quotation,"In the end we will conserve only what we love;we will love only
what we understand;and we will understand only what we are taught."That belief fueled his insatiable drive to
explore the unknown,and to push the boundaries of comfort and routine.
In all of modern-day ocean exploration we've barely scratched the surface-far less than 10 percent of the
salty deep-in any significant way.This should not come as a surprise,considering that the ocean totals 99
percent of our planet's living space.Add to this the complexities of exploration below the surface like increasing
pressures,the density of seawater,the corrosive nature of saltwater on equipment,strong currents,extreme tem-
peratures,a vast unknown geography,lack of light,unpredictable(or unknown)wildlife and man-made risks
like entanglement in fishing nets.
Ocean exploration remains critical.Our planet faces dire challenges,and the seas are stressed,perhaps
almost to a breaking point.We must stay in the water and pursue knowledge and answers as quickly and as
wisely as we can,using safe means to do it.Mistakes will inevitably be made.The Titan submersible tragedy is
just one such example.Let's not make the mistake of not
