Espiritu Santo by Sailboat (Citizen Science Expedition)

Our Standard package delivers the complete field science experience, including hands-on eDNA sampling, live plankton microscopy, all expedition equipment, and guidance from a PhD Marine Biologist. Upgrading to the Premium package takes the science from the beach to the lab, directly funding the rigorous processing of the samples we collect together. This covers DNA extraction, amplification, next-generation sequencing, and bioinformatic decoding, which allows us to create highly accurate wildlife inventories for your specific time and location. Ultimately, the genetic sequences from your expedition are formally published to GenBank (the global open-access genetic database) under your name, cementing your personal, lasting contribution to marine conservation.

Think of eDNA as a genetic barcode left behind in the water. As marine life—from microscopic plankton to massive whale sharks—moves through the ocean, they naturally shed cellular material like skin cells, mucus, and scales. By filtering the seawater and sequencing these "invisible footprints," we can identify which species are present without ever disturbing or even seeing them. This non-invasive technology is revolutionizing marine biology by allowing us to detect rare or endangered species, map hidden biodiversity, and provide crucial early-warning alerts for invasive or harmful species before they can disrupt the local ecosystem.

All our expeditions require a minimum of 6 passengers to confirm departure. If your selected date has not reached this minimum, we will contact you 72 hours before the scheduled departure. At that point, you will have the option to reschedule to a confirmed date, upgrade to a private buyout to keep your current date, or receive a full refund of your deposit.

Swimwear, towel, biodegradable sunscreen, a light jacket or windbreaker (especially in winter), and a sun hat. We provide all scientific gear, snorkel equipment, wetsuits (in winter), and your regional gourmet lunch.

Yes! Families are very welcome. Children under 2 join free (please let us know in advance), and kids of all ages love examining live plankton through our field microscope.

We offer a 100% full refund for cancellations made at least 72 hours prior to your expedition departure date.

During June, July and August each year, we aren't allowed to snorkel at the bigger sea lion colony in Espíritu Santo. However, Balandra has a smaller sea lion colony we can visit year round, and there are so many breath taking places to snorkel during those summer months!

Unlike our speedboat tours, food is not automatically included on the sailboat. You are welcome to bring your own food and beverages (we provide a cooler and kitchen utensils). Alternatively, we offer a dedicated catering service at an extra fee—simply inquire for menu options after booking.
