    Shelly Krueger is the Florida Sea Grant agent for the University of Florida IFAS Extension, Monroe County. Shelly has a bachelor’s degree from Georgia Tech and a master’s degree from Savannah State University in marine science. Shelly will talk about sargassum and a pilot sargassum composting experiment that Shelly has been working on with Michelle Leonard-Mularz at the Key West Botanical Garden.

    This summer, you may have noticed tons of brown organic material washed up on beaches and decaying all over beaches on the Atlantic Ocean. But what is it, really? And why is it appearing on our beaches? It’s called sargassum, and it is brown algae, or seaweed, that floats in massive mats out on the open ocean. The area sargassum comes from is called the Sargasso Sea, which is not a true sea at all, but an area far offshore in the Atlantic Ocean between the eastern coast of Florida and Bermuda.

    The Sargasso Sea and the mats of sargassum that float within it are defined by the dominant ocean currents – the Gulf Stream on the west, North Atlantic Current to the north, Canary Current on the east, and the North Atlantic Equatorial Current to the south, which creates a swirling gyre that contains the sargassum floating out at sea. Frequently, the sargassum gets caught up in one of the currents and escapes the Sargasso Sea.

    If you like to fish, you may have heard these floating algae mats called the “weed line,” and they are fantastic spots to sportfish. Sargassum is actually a very important habitat type out in the open ocean as it provides one of the only places for some species of fish, crabs, and juvenile loggerhead sea turtles to forage and hide from predators. A thick clump of sargassum provides a feast for many species, including birds, and also attracts the larger gamefish who prey upon these species, like mahi and tuna. NOAA Fisheries considers sargassum essential fish habitat for snapper, grouper, gray triggerfish and coastal pelagic migratory species like mackerel.

    In the Florida Keys, when we experience prevailing winds from the south and southeast, these massive floating mats of sargassum that have broken free from the circling gyre of the Sargasso Sea are washed onto shore with the wind and waves. Tons and tons! Unfortunately, the dead and decaying sargassum can remove oxygen from the water and lead to fish kills, smother seagrasses and turtle nests, and can become packed so thick inside the residential canals it can become difficult to get your boat out.

    Historically, washed-up sargassum is one of the ways beaches were created in the Florida Keys, as the accumulation of seaweed along the shoreline helps to keep the sand from eroding and provides nutrients to help enrich the soil. But when the sargassum encounters a seawall or a canal instead of the beach there is little benefit for it decays, sinks, and stinks! Unfortunately, this is a major cause for fish kills because the decomposition of organic matter literally removes the oxygen from the water column.

    Shipwreck Park was established in 2014 for the purpose of creating an artificial reef system off the coast of Broward County, Florida.  It was incorporated and received 501 (c) (3) status in 2015.  The organization has acquired and deployed two vessels since then off the coast of Broward County.  The first was the 324ft Newtown Creek rechristened the Lady Luck in July of 2016 and the second a 103ft tugboat Okinawa in August of 2017. Since inception Shipwreck Park has raised Jay Underkofler$979,000 in donations and spent $956,000 on the deployment of the two vessels and the exploration of new projects. Shipwreck Park is all volunteer organization.

    Jay Underkofler will be talking on the current Wahoo Bay project, taking place at the Hillsboro inlet.

    As a teen, Rob started studying marine life in 1967 and did his first scuba dive in 1969 while living in Hong Kong. Graduated from U. Hawaii with a BA in zoology in 1975. Rob also surveyed Oahu fish populations, collected fish for ciguatera research at Johnston and Enewetak Atolls as an assistant to John E. Randall.

    Moved to Guam in 1977 to pursue graduate studies at U. Guam Marine Lab. Divided time between studies, u/w photography, and employment; earned MS in Biology in 1984. In 1981, founded Coral Graphics and from 1982 to 1995 worked as a fisheries biologist for government of Guam. From 1993 to 2000, served as a consultant with Sumeria for Ocean Life CD-roms.

    Retired in 1995 to pursue photography, writing, research, and consulting. In 2002, moved to s. Florida. Since 2006 has been voluntarily serving with the International Union for the Conservation of Nature (IUCN aka World Conservation Union, Bern, Switzerland) as a member of the Global Marine Species Assessment (GMSA) specialist group of the Species Survival Commission for coral reef fishes. Aug-Nov 2011, conducted fish surveys on Guam for CSA International. Aug 2013, surveyed fishes in Palau marine lakes; Sep-Oct 2016, visiting Professor, Univ. of Montpellier, France for initial work on Atlas and database of coral reef fish distributions. Participated in New Caledonia deep reef and seamount surveys (2019-2023 study), but was locked out after initial trip due to covid restrictions. Has written or collaborated on numerous scientific papers and technical reports on the Micronesian and Red Sea ichthyofaunas, and authored or co-authored several books including Micronesian Reef Fishes (1989-1999), Coral Reef Fishes (with E. Lieske; 1993), Coral Reef Guide Red Sea (with E. Lieske; 2004), Dangerous Marine Animals (with M. Bergbauer and M. Kirschner) and three books on Florida shells (with E. Petuch and/or D. Berschauer). Maintains comprehensive spreadsheets of Indo-Pacific and W. Atlantic fish distributions.

    Rob is currently dividing time between continued faunal studies of Indo-Pacific fishes and books (with co-authors), specifically a Caribbean field guide, and new edition of Micronesian Reef Fishes and continues volunteer work with the IUCN and related consulting work.

    Ambon, the southern gateway to the Maluku Islands has an often brutal history almost as fascinating as the region’s fauna and flora. Our stay there was not originally on our itinerary which was to get to the Damai II for a fabulous 12 day journey that would take us through the tiny volcanic islands of the Banda Sea, the eastern end of the Maluku Islands and on to Misool and West Papua. Once I found out our flights had been rerouted via Ambon, I contacted the newly opened Spice Island Divers to arrange a short stay. Conveniently located less than 10 minutes from the airport, the resort sits on the northwestern shore of Ambon Bay, a 3,000 ft deep bay between two mountain ranges. It is not only a fabulous muck dive site but also dotted with species-rich coral reefs and is an ideal site for blackwater diving, pioneered there by USA’s own Linda Ianniello and Bob Weybrecht. Although we managed only 10 dives in 4 days, we found a treasure trove of critters new to us. Our last day included a special tour of the island with a visit to historical Fort Amsterdam. Of more recent historical interest is the wreck of the Aquila, a Panamanian merchant ship sunk in 1958 by a covert CIA operation with huge cold war implications.

    The morning after our tour we flew to Saumlaki, Tanimbar to board the Damai Dua, our base for the next 12 days. Running at night, diving by day, we visited small islands from three distinct arcs, each with its own distinctive geology and reef development as we crossed the Banda Sea. The Forgotten Islands of Dawera and Dai rise abruptly from deep mountain ranges and are capped with ancient uplifted reefs and presently surrounded by fringing reefs with sheer walls and steep slopes. We then moved on to the volcanically active islands of Nil Desperado, Serua, Manuk and Banda Neira, the only inhabited island cluster. Some of these uninhabited islands are home to huge populations of the highly venomous but completely docile Black banded sea krait (Laticauda semifasciata). These recently emerged islands have volcanic boulder slopes variably coated with corals and other marine life. Sea kraits may be found from the surface to the bottom where they are either sleeping or hunting, often accomapnied by predatory fishes, always ready to snap up prey escaping the snakes. Banda Neira, the home of nutmeg and mace has a fascinating history more brutal than Ambon’s that is well-documented in a wonderful local museum.

    Our next stop, Koon, is a coral atoll at the eastern tip of the long island of Ceram. Its reefs are more reminescent of those of Wakatobe or Micronesia, with coral slopes bisected by chutes of white coral sand.  After an over night transit across the last deep water gap, we arrived at Misool, the southernmost and largest of the Raja Ampat Islands, all on the relatively shallow West Papuan shelf. These islands are the uplifted remnants of ancient coral reefs, much like the rock islands of Palau. Most are surrounded by narrow fringing reefs and shallow shelves bordered by steep coral walls and slopes that end on a sandy sponge and coral shelf at depths of below 100 ft to about 200 ft. As if the coral reef fauna isn’t diverse enough, by being connected to the continental shelves of New Guinea and Australia, the shelf is a bridge to their unique faunas. The most iconic fo these among fishes are the Epaulete and Carpet sharks, always high on my list of photographic subjects. These coastal shelf waters are a bit more turbid than the deep open sea over abyssal depths but make up for it by hosting the richest reef fauna in the world. The added nutrients nourish vast shoals of slivery baitfish and juvenile reef fishes, which attract feeding mantas that may suddenly appear out of the blue. Our trip ended after a 2-day transit punctuated by a final dive at the Fam Islands. The morning we disembarked I counted 21 live-aboards anchored within sight, in the bay at Sorong.  Another shock was the large modern steel and glass terminal complete with jetways and several waiting aircraft, a far cry from the open shack and unfenced runway of 2004, when over the course of 2 weeks,
    only one live-aboard was encountered.

    Black Water Diving in Southeast Florida

    Linda Ianniello has been diving and doing underwater photography for over 30 years. For the past six years Linda has been focusing on black water dives, up to  four times a week locally. A black water dive consists of going six to seven miles off the coast and performing a drift dive in the edge of the Gulf Stream, at night. The bottom is approximately 700 feet deep, but we generally stay in the top 40 feet. It is fascinating to find and photograph the pelagic animals  who spend their whole lives in this environment, the various larvae that spend the early part of their lives here, and the deep water animals that migrate vertically at night to feed.

    Linda will be talking about the mechanics of a black water dive and the variety of creatures that can be found on these dives. Also, how she is using her images for several “citizen science” projects. Linda along with Susan Mears have co-authored and published a book on the subject of the talk titled  
    “BLACKWATER Creatures – A Guide to Southeast Florida Blackwater Creatures."

    Greetings Fellow Under Sea Adventurers!

    Many of you know me, but for new members I would like to introduce myself.

    My name is Clare Anthon. I joined the USA Dive Club in May 2004 and always had the desire to dive, but raising my family came first. After my girls were grown, it was time to get certified. As an active club member, I’ve held positions as USA’s Co-VP of Social, Social Butterfly and for the past 12 years Hospitality Coordinator.

    Overseas diving has been a yearly activity for me. My very first trip in 2005, was aboard the Cayman Aggressor IV. In 2009, I was trip leader for 24 divers on a wonderful adventure to Curacao. The next trip as trip leader was in 2012 with Explorer Ventures Liveaboard to the Turks & Caicos. Curacao was so beautiful the club decided to repeat the trip in 2013, and I volunteered to be trip leader. Along came 2017 and once again, I was trip leader for 18 divers to gorgeous Cozumel. My most recent trip lead was in 2018 with a cozy group of 8 to Boni Bonaire.

    Looking forward to being your Cayman Aggressor V 2022 trip leader. Please join me!

    Sunny regards,
    Clare Anthon

    June 2021 Program

    Under Sea Adventurers Overseas Diving - Nils Jacobsen

    For most of you a detailed introduction of Nils should not be required – anyway, if you are a relatively new member – or you are an older member – that might have missed some of the earlier details – here is a “short” recap:

    Nils had a dormant subconscious desire for diving – just like many other kids at that time having watched years of Jacques Cousteau on black and white TV in Europe. Nils was on a corporate work trip – a 9 ½ weeks world tour in 1992 – doing worldwide software training – back in the heights of the industrial production and design outsourcing. Key stops: S Florida: where HR sent him to Pennekamp Park to snorkel; Singapore: Penang Malaysia, where HR invited him to join a trip to a marine sanctuary – Pulau Payar (in those days – you needed a permit from Malaysia Ministry of Interior to be allowed to go there).  The local company went there to certify scuba divers that had worked 6 months towards their certification. Nils snorkeled in Azure blue water close to 3 feet potato cods and soft coral – and he was sold - committed to get a scuba certification. (Only one small negative – he slept on the beach – with no formal camping gear – and the hotel towels were 4-6” short of protecting his feet from mosquitos); He took a PADI class in Sept 1992 (he was the only one – changing from shirt and tie – to speedos… before jumping in the pool – a professional travel agent – nailed it – “you are either gay or European” [#2=TRUE]; back in 1993 Denmark he pursued a CMAS certification – (incomplete due to excessive travel in 1993).

    During 1993 Nils got to dive Indonesia, Malaysia, Red Sea, Bahamas and S Florida. Nils got his second PADI certification – Advanced - in Johnson State Park in Hollywood. Nils got an offer to move to US late in 1993 on a corporate relocation – the choices were Arizona :-(, Chicago :-( or S Florida -:) – and the rest is history.

    Nils met USA dive club in the spring of 1994 during a reef clean-up dive on “Lady Go Diver” (the first boat) - joined USA dive club for lunch – and was invited to a club meeting. Nils joined the club later in 1994 – was Newsletter editor for a few years (PageMaker on a PC – in slow motion – real stamps – and delivered by US Postal Service) before becoming VP of overseas diving late 2002 – and his first assignment was to go to DEMA in Miami, Nov 2002 and book the Ocean Rover for the Thailand trip.

     More Recently

    On land Nils is always easy to find/easy to follow – as he is “always under the hat” – so he is never lost!

    In non-diving settings – he shows a wide range of formality levels and dress-codes:


    Underwater Nils is most often dressed Ninja-black, looks like he is carrying a small dive shop and most of the time hidden behind a large camera:

    The presentation will cover pictures from our past 3 Fiji trips:

    • 2008:
      • Nai’a
      • Kadavu
    • 2015:
      • Aggressor
      • Waidroka
    • 2020:
      • Nai’a –only; truncated by Covid-19 evacuation

    The rescheduled trip to Volivoli: Now: May 10-17, 2022 - We still have spots available.

    The Turtle Hospital

    Hello My name is Christine Watt.

    My love of turtles began at the early age of 14 in NY, when I found painted turtles in my back yard.

    In my twenties, I moved to Florida where I saw an advertisement in the local paper, ‘make a reservation to watch a female loggerhead nest at night!’ Interested, I called to reserve a spot; but the guy in the office was a newbie, it was his first day working and so he serendipitously registered me for a turtle nesting educational guide training by mistake! Ever since that pivotal moment, I’ve served as an active member of the Sea turtle Preservation Society as a permitted guide for night time turtle nesting watch and was on the stranding team. That was for almost 16 years, and since then I’ve continued to work in the Sea Turtle world as an educator, a permitted guide, and turtle nest surveyor.

    While attending a Sea Turtle Symposium in 2002 I met Richie Moratti, the founder of The Turtle Hospital in Marathon, FL one of the largest and first Sea Turtle Hospitals in the world. I would also see him regularly at FWC permit holders meeting. 7 seven years ago, I asked him if I could volunteer at the Turtle Hospital during the summers as I was working in a school and had summers free. Richie said “we couldn’t have volunteers at this time, but we are looking for someone to work in our educational department.”

    The rest is history, I left the school systems after 14 years to become an educator here at The Turtle Hospital and I’ve never looked back.

    I currently hold a nesting position here in the Keys as a nesting Surveyor in Marathon. 2021 Nesting season will be my 6th year.
