- Across Geography and Time: Kamau Sadiki Dives With a Purpose
February 2023
Kamau Sadiki is a board member and lead instructor with Diving With a Purpose (DWP), an international
organization dedicated to the conservation and protection of submerged heritage resources. DWP provides
education, training, certification, and field experience to adults and youth in the fields of maritime
archaeology and ocean conservation. The organization's special focus is the protection, documentation,
and interpretation of African slave trade shipwrecks and the maritime history and culture of
African-Americans who formed a core of labor and expertise for America's maritime enterprises.
Sadiki is featured in the Netflix documentary “Descendant,”
which follows the descendants of the slave ship Clotilda, the last slave ship to smuggle
African captives into the U.S. more than 50 years after the Atlantic slave trade was abolished, as they
try to figure out how to best honor their ancestors. Sadiki participated on the field mission that
confirmed Clotilda's discovery in the Mobile River in Alabama. He has participated in the
archeological search, survey, and documentation of five known slave ships: Guerrero in John
Pennekamp Coral Reef State Park in Key Largo, Florida; Sao Jose Paquete de Africa off the coast
of Cape Town, South Africa, Fredericus Quantus and Christianus Quintus in Cahuita
National Park, Costa Rica, and Clotilda.
He has also worked on multiple shipwreck sites around Mozambique Island, Mozambique; St. John, U.S.
Virgin Islands; Biscayne National Park in South Florida; and in NOAA's Thunder Bay and Florida Keys
national marine sanctuaries.
This interview has been edited for length and clarity.
Please tell us about your upbringing and what or who first ignited your interest in maritime
archaeology?
Actually, my interest in maritime archaeology developed in the latter part of my life. I was born and
raised in the rural south where I spent many summers between school years swimming in ponds and the local
segregated pool. I lied about my age and joined the Boy Scouts when I was 10-years-old, earned a swimming
merit badge, and spent many weekends camping out and enjoying the rivers and lakes that were in our
camping environment. So, I was nurtured around water and always had a love for it.
I earned my initial scuba diving certification in 2006 from Dr. Albert José Jones, the iconic scuba
pioneer who has trained thousands of African American divers, after a serendipitous meeting in the
Dallas-Fort Worth airport. Through the Underwater Adventure Seekers, a dive club established by Dr. Jones
in 1959 in Washington, D.C., I got connected with Diving With a Purpose (DWP). I consider myself a student
of African and African American history. So, when I heard that DWP was focused on the stories of
shipwrecks that participated in the Trans-Atlantic Era of African Enslavement (TEAE), it was a natural
attraction. I took the DWP archaeology course in 2007 and now I'm currently a board member and lead
instructor with DWP. I've participated in numerous archaeology field missions with DWP, which has afforded
me the opportunity to dive on five known or suspected TEAE shipwreck sites, two most notable are the Sâo
José Paquete de Africa, the first archaeologically documented shipwreck in which Africans lost their lives
and the Clotilda, the last known ship to bring captured Africans into the USA with the intent to enslave
them. After retirement in 2017, I fully submerged myself into the work of DWP and maritime archaeology.

Diving With a Purpose has fostered education and professional training to encourage greater
diversity and inclusion within the field of maritime archaeology, including youth programs and
partnerships with local communities and NOAA's Office of National Marine Sanctuaries. What is the driver
for this particular focus?
Probably the most important program is our Youth DWP program where we take young people ages 12 to 20
and teach the skills of underwater archaeology documentation, coral reef restoration/conservation and the
importance of the marine environment. Since 2014, DWP has trained more than 150 youths from diverse
backgrounds, virtually at no cost to the youth and their families. It is from a keen recognition that we,
as older adults, won't be able to do the work of DWP forever. So, it becomes critically important to
engage young people, not only to sustain the program well into the future, but more importantly, to
provide them an opportunity to learn and develop critical skillsets that will be of value to them as they
mature and take on the challenges of life. As we identify shipwrecks that were involved in the TEAE, it is
imperative that we engage the local communities, especially descendant communities, as part of the
outreach effort to build capacity, connect them with their cultural heritage and create opportunities for
engagement in controlling the narratives of these historical events.

According to the Trans-Atlantic Slave
Trade Database, around 35,000 ships were used to bring over 12 million enslaved Africans across
the Atlantic, never to return. Nearly 2 million captives would perish on their journey across the
Atlantic. What motivates you to locate, document, and interpret sites and stories associated with
arguably the most horrific and extensive trade in humans in world history.

behind them. This vessel was captured by the USS Mohawk and brought into port at Key West,
Florida. Image: Library of Congress
My motivation comes from a deep desire to restore memory, to correct injustices, and an embodied sense of
ancestral connectivity. Those 2 million Africans, not to mention the millions more that died in Africa,
the Caribbean, and the Americas as a consequence of European enslavement, are restless souls who have
never been laid to rest ritualistically. They have yet to rest in peace. I think it is important to
appropriately memorialize those Africans, keep them in memory, so that they are never forgotten, even
those whose specific names we will never know. So, until they are acknowledged and memorialized with
respect, there will always be work to do.
How do you approach the story of the global slave trade, a story that for many African Americans
is wrought with deep trauma, pain, and sadness, but a story that some people consider ancient history,
irrelevant to people living today?
The Trans-Atlantic Era of African Enslavement caused massive historical trauma practically on every
continent. The descendants of the victims of that enslavement are deeply connected to the horrific
experiences suffered by our ancestors through epigenetic trauma, which is played out in behaviors we see
today, such as identity denial, cultural distortions, and victims blaming and attacking other victims. If
we remain disconnected from our ancestors, we will always have this huge hole in our souls. History is
very relevant to the present and if not studied and acknowledged, victims of history will always wander
around lost and misguided. As noted historian, Dr. John Henrik Clarke stated, “History is a clock that
people use to tell their political and cultural time of day. It is a compass they use to find themselves
on the map of human geography. It tells them where they are but, more importantly, what they must be.”
Truth can be painful but necessary if we are to restore our humanity.
Of the slave ships that you have researched and documented, is there one that holds particular
significance to you?
Well, each one of these shipwreck sites have very unique stories to tell and are critically important to
the materiality of the Trans-Atlantic Era of African Enslavement. However, there is one shipwreck that is
very special in its uniqueness and that shipwreck is Clotilda, the last known ship to bring
captured Africans into the United States with the intent to enslave them. What makes Clotilda so unique is
not only that it was the last known ship of the enslavement era but it is the only shipwreck in which more
than 70% of the actual ship remains intact. This makes it hugely archaeologically important. You can
actually see the outline of the ship in sonar images and, more importantly, you can see the actual cargo
hold where the 110 Africans endured the Atlantic crossing. Of the 12,000 ships that were involved in the
TEAE, there is no other artifact in the historical record like Clotilda. So, it carries a very
special significance and must be preserved as a central piece of the narrative of the Clotilda
story. I'm humbled to have had the honor to work on the wreck site of Clotilda and with the
descendant community of Africatown, a town established after the Civil War by 32 of the enslaved people
who were on board Clotilda.

Knowing that Clotilda transported 110 captive men, women, and children from Africa to
the United States, mere commodities to be bought, sold, and traded, what was your mental state of mind
as you prepared for your dive inside the ship?
Since my very first dive on a shipwreck that was involved in the enslavement of my ancestors, I've
noticed that I connect very deeply, emotionally and psychologically, with the horrific trauma that is
embedded in these vessels. I tend to embody that trauma and I can feel it. We dive on these shipwrecks to
do science and archaeology, but there is another dimension that cannot be overlooked, at least for me.
Embedded in these artifacts are unthinkable traumatic experiences and when I touch them, that energy
reverberates through me. You can actually “feel” their screams and voices. When I dive on these
shipwrecks, I have to ritualistically acknowledge the pain and suffering of my ancestors and find a way to
calm myself to be able to “listen” and connect with the experiences that the artifact/shipwreck
represents. So, for my first dive on Clotilda, a dear friend of mine, Sabrina Johnson and I,
composed an Ancestral Prayer that I recited before entering the waters of the Mobile River to start the
dive on Clotilda. That prayer was a communication with the spirits of the enslaved Africans who
experienced the trauma of that journey. It was our embrace and statement of resistance and resilience.

Throughout the “Descendant” documentary, we see members of the community reckoning with the story
of Clotilda, including discussions about community redevelopment and opening a museum. What are
your hopes for communities like Africatown, Alabama, to preserve and protect their history for current
and future generations? What are some of the challenges facing these communities?
Ongoing systemic racism has devastated these communities but, in spite of, they have resisted and shown
incredible resilience over the years. Economic and environmental racism is so blatant in many of them,
particularly Africatown. The “Descendant” documentary has really helped shine a bright light on the
Africatown story. My hope is that Africatown flourishes again and its people reap the economic benefits of
their own story. I would also like to see environmental justice and equity centered in collaborative
actions that will be taken to deliver clean air, water, and land to produce a healthy, prosperous,
revitalized community.

Forty-one of the 561 enslaved Africans aboard Guerrero died when the Spanish slave ship
sank off the Florida Keys in 1827 in waters that today comprise Florida Keys National Marine Sanctuary.
How confident are you that Guerrero will be
conclusively located?
As you mentioned, Guerrero sank in 1827, on December 19th. We basically know the general
location where Guerrero sank but the exact location is still being investigated. I'm pretty confident that
the exact location will be found in the near future. Extensive archaeological surveys and documentations
have been done across most of the area of the suspected sinking location. More work has to be done to
basically eliminate or verify material possibilities of the location of Guerrero. DWP hopes to
complete that work over the next year or so. We just have to wait and see what the results of those
investigations will provide in answering the questions of where the remains of Guerrero actually
are located.

Speaking of Guerrero, Diving With a Purpose started 20 years ago when members of the National Association of Black Scuba Divers were interviewed for a
documentary about the ship. Considering how you started, where does DWP see itself 20 years from
now?
That's a difficult question. One of the prime motivators for DWP engagement in this type of work is
because of systemic inequities that continue to exist in our society. So, in one sense, I hope 20 years
from now those racial/social/economic, etc. inequities won't exist. However, given the current climate,
I'm not too optimistic about that. I am hopeful that 20 years from now DWP will have grown to the point of
having a well endowed brick-and-mortar institution that offers a wide range of maritime archaeology and
marine environmental courses and programming with a continued focus on youth. This institution would be an
international training center providing instruction for a global community. Personally, it is my hope that
20 years from now DWP will be at the forefront of institutions studying the materiality of the
Trans-Atlantic Era of African Enslavement and have archaeologically documented and told the stories of at
least five additional shipwrecks during that era.

National Marine Sanctuaries, the workshop provided the partner organizations with new competencies and
skills they can share within their networks. Image: Robert Schwemmer/NOAA
What do you want your legacy to be?
That I was an inspiration for good. That I put in the consistent work to destroy the global system of
white supremacy, replacing it with a system of justice where no one is mistreated…and that I made my momma
proud!
