Phase 1 Antarctica 2024

In Phase I Antarctica 2024, Michael Carvalho, an environmental attorney, Explorers Club National Member and expert polar ice SCUBA diver, will embark on his third Polar expedition and second expedition to Antarctica, in Feb – March 2024, leading the environmental policy assessment of POLEs in the Southern Ocean and Antarctic Peninsula. Mr. Carvalho will serve as the Senior Science Policy Advisor to The Explorers Club Flag Expedition’s scientists who will assess food web dynamics correlating aspects of increasing rates of glacial run off, temperature and decreased salinity with the complex biodiversity and population densities of foundational microplankton, the predators and prey of krill, a pivotal food web member upon which so many higher polar life forms depend. Specifically, scientists, researchers, and explorers on the team will collect and document microscopic plankton species, eDNA samples, physical oceanographic data, and underwater photogrammetry.

A unique aspect of the POLEs Expedition is the well-planned deliverables. The scientific data will inform a policy assessment paper that Carvalho will be preparing as a critical deliverable of the POLEs Flag Expedition.

Mr. Carvalho has experience serving as a Delegate for North America to the United Nations Environment Assembly, and his expertise will provide critical assessment of the Science-Policy Nexus of The Treaty of Antarctica (Madrid Protocol). This work is important because scientists will be assessing whether the policy goals are being met halfway through the fifty-year life of the Treaty. The policy assessment will include recommendations for improvements to better reflect the current science in the Southern Ocean and Antarctic continent.

About the Scientific Work – The Intersection of Science, Policy and Education

The types of scientific research that will take place on this expedition are diverse and include:

Live Plankton Photomicroscopy allows immediate identification of known planktonic species, as well as documentation of novel species of microscopic freely swimming plants and animals or “zooplankton and phytoplankton” which have not been systematically studied in shallow Polar coastal environments. Thus, the POLEs Flag Expedition is an historic and pioneering effort made even more valuable by the inclusion of a longitudinal element over 4 distinct phases in which biodiversity data will be gathered over the course of a multiple-year time series. This work will be directed by University of Hawaii research professor and Explorers Club National Fellow, Dr. Petra Lenz, with assistance from Dr. Angel Yanagihara.

Community DNA allows the identification of organisms comprising a community at a specific time and location. Samples will be collected, preserved, and analyzed using conventional PCR and other molecular biological approaches such as metabarcoding, meatranscriptomics, and single cell RNA sequence analysis under the direction of Dr. Lenz. Additionally, Environmental DNA (eDNA) samples will be prepared using NOAA protocols and banked for future analysis.

Physical Oceanography is the field of study that deals with mechanisms of energy transfer through the sea and across its boundaries, and with the physical interactions of the sea with its surroundings, especially including the influence of the seas on the climate of the atmosphere. The Expedition will assess the complex physical interplay between wind, waves, water density, and pressure by using special sensors to collect water samples from various locations along the Antarctic Peninsula. Glacial run off nascent coastal zone sea temperature, salinity, and geochemistry will also be assessed in GIS mapping surveys to correlate with the biodiversity effort and eDNA collections. The team’s efforts will be supervised by Evan Kovacs, Explorers Club National Fellow, inventor, and former researcher from Woods Hole Oceanographic Institution.

Underwater Photogrammetry involves SCUBA divers using square meter frames to photograph existing features for later analysis at multiple, geolocated positions.

The outcomes of this work will allow scientists to gain a better understanding of existing conditions, comparison to previous studies, and establish a data set that will form a baseline for comparisons in subsequent Expeditions. The eDNA collection will be replicated in subsequent years in the Arctic and Antarctica to track changes. The results of the POLEs Expedition will be shared with students in the Gulf of Maine who are disproportionately affected by Climate Change.

How You Can Help

To realize the full educational potential of this expedition, the Expedition is looking to raise $50,000. The Expedition has established a giving fund through the University of Hawaii Foundation. Your tax-deductible contribution will provide staff time for Expedition planning, sampling equipment, and curriculum development.

Michael Carvalho, who will be leading the Science-Policy efforts will self-fund his travel and vessel costs, but assistance is needed to support the science educational objectives of this Expedition.

Cayman Islands Government Responds to Stony Coral Tissue Loss Disease (SCTLD) Impacts

By Michael P. Carvalho, Esq. and Christopher J. Miller, B.S., M.S Eng.

November 6, 2023 – Stony Coral Tissue Loss Disease (SCTLD) is a deadly coral disease affecting over twenty-five species of hard coral resulting in rapid tissue mortality and death of entire colonies. The disease was first reported on Florida’s reefs in 2014 and has subsequently spread throughout multiple countries in the Caribbean, to include the Cayman Islands, due to its high transmissivity. SCTLD causes lesions to appear on hard corals following increasing bleaching events associated with dramatic increases in surface water temperatures caused by Climate Change. Infected corals rapidly lose live tissue and entire colonies can be wiped out in weeks to months (Precht et al 2016). The Cayman Islands government is particularly concerned about the spread of SCTLD from Grand Cayman where the disease is now widely established to Cayman Brac and Little Cayman, where SCTLD has not yet gained a foothold.

Cause

The cause and method of SCTLD transmission are currently unknown but are the subject of intense research. Previously, researchers believed that SCTLD is a bacterial pathogen that grows rapidly and is transmitted by direct contact and ocean currents. (Aeby et al, 2019). More recent research suggests that a viral pathogen may be disrupting the coral-zooxanthellae symbiosis, a type of photosynthesis algae living in coral tissues. (Landsberg et al 0202; Work et al 2021). There is no known cure for SCTLD, which has a mortality rate of 60%-100% (Precht et al 2016), although studies are underway to determine whether topically applied antibiotics may be effective.

Affect

SCLTD negatively affects coral density and species diversity, reducing the overall health of coral reefs and resulting in significant degradation to coral reef ecosystems. The loss of coral reefs (already imperiled by rapidly warming ocean surface temperatures and physical damages from intense weather events) affects not only the health of the reef, but also the myriad of economic interests they support. Such interests include tourism, coastal protection, food, and recreation, among others impacts. In the Cayman Islands, tourism is a mainstay of the economy, accounting for approximately 70% of GDP. (Moody’s Analytics, www.economy.com/cayman-islands). With the main sources of income in the Cayman Islands consisting of financial services, tourism and real estate sales and development, the loss of once pristine coral reefs upon which much of the tourist economy is based, would be devastating to the economy.

Response

All hands-on deck. Local governments throughout the Caribbean are collaborating with regional and international partners to continue to study the causes and effects of SCTLD on coral reefs. The Cayman Islands Government Department of the Environment (DoE) is “…actively training volunteers on disease identification and how to use treatment options while expanding our citizen scientist reporting efforts to engage the public in helping us identify diseases coral.” DoE regularly collects samples for epidemiological research and applies topical treatment of Amoxicillin + Base2B on affected corals within defined study areas. (doe.ky/marine/sctld.).

The Cayman Islands government is also engaged in efforts to grow new coral using fragments harvested from healthy reefs and grown on “coral trees” suspended in the water column in nurseries. https://missionblue.org/2017/03/cayman-islands-coral-nursery-conservation-program/

DoE is actively engaging scuba divers and fishers who are being relied upon not only of their ability to identify and report diseased corals, but also to avoid transmission of SCLTD by disinfecting dive gear and bilge water, as pathogens may survive on for extended periods and can transmitted to other locations. Disinfection can be achieved through using a 1% bleach solution, ammonia-based disinfectants, or antibacterial dish soap. DoE requests that divers and snorkelers consider renting local dive gear, avoid visiting healthy sites after visiting diseased sites, disinfecting gear between sites, and disinfecting bilge water between Grand Cayman and the Sister Islands (Little Cayman, and Cayman Brac) at least one-half mile offshore and away from coral reefs.

The Lecture Series is part of a MET (Massachusetts Environmental Trust) grant awarded to Salem Sound Coastwatch to study the issue of turbidity in Salem Harbor over the next two and a half years.  Turbidity, which is cloudiness in the water column, affects the ability of the water to sustain marine life.

On  January 29, 2014, Dr. Robert Buchsbaum, conservation scientist with Mass Audubon, gave an illustrated presentation on the fascinating arctic birds that are only visible in Salem Sound during the winter. These seasonal guests come to local waters for the abundant food provided by Salem Sound’s fish, snails, mussels and underwater plants.

Then in February, Dr. Brad Hubeny, professor of geologic sciences at Salem State University, will talk about “History Revealed by the Sea Floor.” Hubeny’s research includes using sediment records to reconstruct pollution and human influence on natural water bodies.

In the third session, “Changing Climate, Changing Fishes,” Dr. Mike Armstrong of the Massachusetts Division of Marine Fisheries will talk about the decline of flounder, the burgeoning squid population and the changing species of fish resulting from changing water temperatures.

 The series wraps up in April with “Shellfish, Shellfish Everywhere and Not a Clam to Eat” — a look at Salem Sound’s productive, but not edible, shellfish beds, by Barbara Warren of Salem Sound Coastwatch.

“Salem Sound’s natural resources play a huge role in the ecological, social and economic life of our region,” said Warren, Coastwatch’s executive director. “This is a wonderful opportunity to learn about our great neighbor, the ocean.”

To learn more about this lecture series, please go to: Underwater-in-Salem-Sound Lecture Series.

This Lecture Series is funded in part by a grant from the Massachusetts Environmental Trust (MET).  MET is funded through the sale of environmental license plates. Every Massachusetts driver who purchases one of the “Preserve the Trust” license plates is contributing to the Trust and to the state’s environmental well-being.
