I am the inventor of SeaweedPaddock a deep water Sargassum farm with biofuels as the end use. Our multidisciplinary team was funded by the USA’s DOE ARPAe MARINER program. We are at a TR level of around 4 and our TEA is positive for further development. if you wish to contact me please do so at info@seavac.org 01:44:27 VALENTINA CACCIA: We can talk about products at Sargassum Lunch time 12-1pm. Martin stay for that section please. 01:46:31 John milledge: The Algae Biotechnology Group at the University of Greenwich is researching “Sustainable solutions for Sargassum inundations in Turks and Caicos”, funded by Darwin Plus. 01:47:00 Emilio Lopez: @john, thanks for sharing! 01:47:46 Emilio Lopez: Any questions about Remote Sensing Monitoring that you'd like to ask Joaquin? Please add to this chat. 01:48:14 VALENTINA CACCIA: Welcome people from DERM, NOAA, RSMAS, FIU, NOVA, etc.. 01:50:49 Gaby Mayorg Adame: Can you share the portal/webpage to access the products? 01:51:09 VALENTINA CACCIA: Questions for Joaquin? 01:51:37 Julio Morell: Thanks Joaquín. 01:52:05 VALENTINA CACCIA: Both webinars are recorded and shared in our website. 01:53:00 Raiza Perrault: Miami-Dade County needs a comprehensive managing plan that will include scientific studies and regulations for uses and disposal of Sargassum. 01:53:39 David Die: I am not sure that the slides are advancing! 02:00:14 John milledge: Martin, we have been working on the challenges biogas production for both S. muticum and pelagic Sargassum 02:02:37 VALENTINA CACCIA: Any questions for Josefina? please post them here 02:04:24 Gaby Mayorg Adame: Is the sargassum transport model specific for some ocean circulation model? What programing language does it uses? 02:05:01 David Die: Josefina: will you be attempting to model evolution of sargassum mats (dynamic shapes of the mats) or will the model consider an "average sargassum shape" 02:05:48 Ligia Collado Vides: Great talk Josefina, 02:05:54 Julio Morell: Josefina, which hydrodynamic model was used in your experiments in Puerto Rico and Fla 02:06:29 Gaby Mayorg Adame: Josefina, does the model consider fragmentation of the elastic shapes? 02:09:10 Ligia Collado Vides: Helena and Afeefa, do you make a difference between different Sargassum species? 02:10:16 Helena Solo-Gabriele: Hi Ligia.... Yes and thank you for your help in identifying the species. We do not see a species effect on the bacteria levels. 02:12:04 Ligia Collado Vides: This is an amazing study 02:12:36 Alberto Pisani: have you correlated the big spikes in bacteria to large rain events? 02:15:45 Ligia Collado Vides: could we recommend to use a different management of the Sargasso on beaches? 02:16:41 VALENTINA CACCIA: Afeefa please clarify about dry seaweed is a source of bacteria. 02:18:26 Afeefa Abdool-Ghany: We classify the seaweed as being dry based on the moisture content. This tends to be the seaweed that is left on the beach and begins to dry. 02:20:58 VALENTINA CACCIA: The source of Fecal bacteria are humans, dogs, birds, other animals. Seaweed is were they tend to accumulate becuase it is their food source. 02:23:04 Emilio Lopez: Any other questions for Dr. Solo-Gabriele and Afeefa Aleema? 02:23:20 Emilio Lopez: Questions for Dr. Joe Serafy? 02:28:20 John milledge: Arsenic levels in Sargassum can be high; Milledge, J.J.; Maneein, S.; Arribas López, E.; Bartlett, D. Sargassum Inundations in Turks and Caicos: Methane Potential and Proximate, Ultimate, Lipid, Amino Acid, Metal and Metalloid Analyses. Energies 2020, 13, 1523. 02:30:44 VALENTINA CACCIA: Wonderful presentations! Thanks for the great research 02:31:01 Philippe Miron: Here is the contact information: 02:31:03 Philippe Miron: https://www.fisheries.noaa.gov/contact/joe-serafy 02:31:40 Lowell Iporac: Wonderful talk Joe! I wonder how, at a field level, these amphipods facilitate detritivory of Sargassum. Can these amphipods provide that ecosystem service of reducing Sargassum biomass at the beaches? And to what extent? 02:34:02 Helena Solo-Gabriele: Hi John.. Thank you for the arsenic reference. 02:34:11 Martin Sherman: Dr. Serafy are there any plans to look at the gut flora of these arthropods? 02:34:39 Steven Leidner: in the open sea what are the biologic impacts/benefits of sargassum mats/fields ? 02:36:12 Martin Sherman: Dr. Olascoaga, in healthy Sargassum at sea which is dominant and to what degree: Wind or currents? How does increasing velocity of either change the relationship? 02:44:16 Emilio Lopez: To join SargNet email lipor001@fiu.edu 02:46:09 Ulises Jauregui-Haza: Thank you Ligia, very nice presentation! 02:46:23 Kalim Shah: Thanks! 02:47:36 Danielle Irwin: Arsenic levels in beach sand often comes to light in South Florida associated with beach nourishment projects. Regulators don't fuss much about it (other than one project I can think of in Surfside) as it is known to them as a background level. Thoughts on Sargassum being the source? 02:47:42 David Die: to Joe Serafy: was the density of amphipods at all related to the volume/biomass of sargassum? Is the density of amphipods independent of the density of sargassum? 02:48:33 Helena Solo-Gabriele: Hi Ligia.... Fascinating presentation and thank you for the emphasis on arsenic accumulations. The citizen science work to document Sargassum strandings is highly valuable. 02:50:11 Sabine Engel: Thank you Ligia, very nice presentation. As is a problem, do you also have info on H2S (impact) 02:51:44 Ligia Collado Vides: Sabine, that is incredible important but I do not have that information 02:53:31 Georgina Bustamante: One of the best webinars I have participated on in the last month. Thanks. 02:55:20 Emilio Lopez: Thanks, Georgina! 02:55:58 Duane Bennish: Very nice presentation Joel! 02:56:14 VALENTINA CACCIA: Thank you for all your questions, please stay for lunch time 12-1pm to answer all questions and interact with your ideas 02:56:46 Gaby Mayorg Adame: Joel, we saw barriers in Puerto Morelos causing retention of dense brown water (I call it dissolved sargassum crap, maybe it has a proper name already)... the areas without barriers look cleaner... I assume barrier need proper maintenance including eventual opening? 02:57:22 Alejandro Bravo: Excelent presentation Joel, congratulations and thank for being so clear in exposing the barriers method. 02:57:23 VALENTINA CACCIA: Great Presentation Joel, Ligia, Afeefa, Ligia, Josefina, Joaquin, Joe Serafi, all presenters.. 02:57:29 Kevin Montenegro: All the presentations were well done and very informative. Thank you, everyone! 02:57:47 Joel Gonzalez: Gaby, you are right, barriers must go along with cleanning program. you can´t just put a barrier there an leave it unattended.. 02:58:25 Alejandro Bravo: I cannot see the presentation, ¿it´s only me? 02:58:37 Emilio Lopez: Any questions for Joel Gonzalez or Duane Bennish? 02:58:41 VALENTINA CACCIA: Only you Alejandro 02:58:53 VALENTINA CACCIA: I am seeing the ppt 02:58:58 Alejandro Bravo: ok 02:59:03 Alejandro Bravo: I see it noy 02:59:05 Alejandro Bravo: now 03:03:13 robert moser: If ANYONE is in need of a location to do research in the Florida Keys (Lower Matecumbe Key), please let me know. We have over 1 mile of beach (and canal) which are regularly inundated with sargassum events. Accumulation is at times 50 feet wide by well over 12 inches deep. It is approximately 90 minutes from Miami. We have been documenting these inundations for many years and can provide pictures. Thank you. Robert@RobertMoser.com 03:03:48 Danielle Irwin: Seems to me that the most holistic way to manage Sargassum on Florida's beaches given our regulatory framework is to keep it in the system while balancing the management priority of each particular beach. State parks leave it in place. Urban beaches collect and mix, bury, or remove it. If removing it, we should consider beneficial uses (Ft. Lauderdale composted it, if I recall) or relocating it far enough offshore that it moves on out. Relocating it to potentially cause an adverse impact elsewhere could be an issue, however. 03:04:15 Alejandro Bravo: Robert Moser: ¿is it allow to put barriers in Florida? 03:08:28 Duane Bennish: Duane Bennish dbennish@elastec.com 618.384.2787 03:08:46 Duane Bennish: Barriers are used for seaweed in Florida 03:09:04 Duane Bennish: Permitting through DEP soon....upcoming weeks. 03:09:58 Ligia Collado Vides: @Danielle Irwin, I think we need to explore the possibility to work on supporting the creating of sand dunes. Texas has good experiences. They has large blooms in 2013-14. I think is a win situation to help reduce the erosion . 03:11:40 Danielle Irwin: @Ligia Collado Vides - Great idea! 03:13:39 VALENTINA CACCIA: Please get your lunch and stay until 1pm for continuing the conversation 03:15:56 Ligia Collado Vides: Valen, I have already a meeting at 12:30, I can stay some 15 minutes 03:17:16 VALENTINA CACCIA: ok Ligia. Thanks all for your time. The ones that can stay please do it. 03:19:20 Danielle Irwin: My understanding is that the barriers are not in our coastal waters, they are in the back bay waterways. Coastal placement of booms brings additional regulatory burdens to the feasibility. 03:20:40 David Die: Helena, Are the indicator of bacteria load the same for sand and water? Is the risk to health the same regardless of the material that humans get in contact with? 03:21:52 Georgina Bustamante: Is the sand loosing its mostly inorganic nature with mixing? integrating? 03:23:29 Gaby Mayorg Adame: Is anyone studying the composition, ecosystem effects and fate of the dissolve organic matter that creates the dense brown water after sargassum decays? 03:23:31 Helena Solo-Gabriele: We are measuring the same indicator in the water as in the sand. The indicators are indicators and not direct measures of pathogens. With levels of pathogens, risk assessments can be conducted depending upon route of exposure (water versus sand). So the short answer to David Die's question is that yes, the same bacteria is measured and the information can be used to evaluate possible exposures through sand versus water. 03:23:38 David Die: In KB management of sargassum includes removal and dispossing of the mixture at the neighbouring sand dunes. Is this mixture of sargassum and sand good for dune vegetation growth and dune growth? 03:24:31 robert moser: to repeat....If ANYONE NEEDS a RESEARCH LOCATION in the Florida Keys (Lower Matecumbe Key), please let me know. We have over 1 mile of beach (and canal) which are regularly inundated with sargassum events. Accumulation is at times 50 feet wide by well over 12 inches deep. It is approximately 90 minutes from Miami. We have been documenting these inundations for many years and can provide pictures. Thank you. Robert@RobertMoser.com 03:24:46 Ligia Collado Vides: Understanding thresholds is a very important task, and also the accumulative rate, an eventually legacy of that accumulation through a year, or several years. This will be a very difficult research question to address. 03:25:11 Joel Gonzalez: David, not really, it depends on the ammount of sargazo....we have seen when there´s large ammonuts burried, it kills all the vegetation 03:26:36 Philippe Miron: @David-Die, sargassum has been used has a fertilizer in different locations, but we have to be careful and perform chemical analysis to make sure no heavy metals are present before usage. 03:30:13 Shelly-Ann Cox: Are entrepreneurs in Florida exploring Sargassum uses? 03:32:03 Helena Solo-Gabriele: Hi Emilio... Thank you so much for the opportunity. I need to sign off due to a conflict with another meeting. Please call on Afeefa on questions about the bacteria. 03:32:12 Alberto Pisani: Is there a collaborative effort between affected countries (US, Mexico, Caribbean nations) to work together and provide funding to Brazil, horn of Africa, or other nations in the river basins believed to be feeding the excess nutrients feeding the sargassum belt in order to develop nutrient reduction targets and strategies that may hep address this issue at the source over the long term? 03:34:47 VALENTINA CACCIA: Hi Alberto, Region Collaborations are being developed along the time. We need to be all open to bring these collaboration to FL 03:36:25 VALENTINA CACCIA: Stay for lunch to interact and exchange ideas 03:36:27 Emilio Lopez: All, please stay for the lunch hour if you can! 03:36:40 Joel Gonzalez: Thank you evryone, and specially to the organizers. Due to another meetig, I will have to leave this webinar... feel free to contact us at 03:36:48 Joel Gonzalez: jjgos@desmi.com 03:36:59 Joel Gonzalez: @Alberto. Not in that sense, no. In order to reduce nutrients reléase in Brasil and Africa, you would have to interfere in sooo many spheres which are well known like clearcutting of the tres, excessive agriculture production and land exploitation for the same use, excess cattle production... 03:37:27 Ligia Collado Vides: Thank you very much all of you!!!!!! Thank you organizers!!!! We need this type of interactions 03:37:41 Martin Sherman: Thank you everyone! 03:37:52 Emilio Lopez: Thank you to all presenters! 03:38:54 Emilio Lopez: This chat is more of an open forum. All, please feel free to share on chat if you want to speak as well. 03:41:26 Emilio Lopez: Would anyone else like to speak? Please add comment to chat so Valentina can call your name. 03:42:24 Una Savic: Thank you to the presenters! 03:44:11 robert moser: QUESTION? Has anyone created a database to exchange/share data based on all the different ideas/solutions....ie.. burning at sea, dune creation, composting, barriers, collecting, churning, anthropoids, fertilizer affects, management etc.... 03:45:37 Ligia Collado Vides: It was a great meeting all. I have go to another meeting. Thank you very much. I hope we will also have access to the recording of the final conversation. 03:46:32 Emilio Lopez: If anyone would like to contact me about solutions and technologies to address Sargassum, my email is Emilio@soptechint.com www.soptechint.com 03:47:42 VALENTINA CACCIA: Anyone to participate and exchange ideas? 03:49:28 Duane Bennish: Website Pablo? 03:51:45 Joaquin Trinanes: I thoroughly enjoyed participating in his webinar. Thank you for inviting me. I have to leave but feel free to contact me in case you have any question or need further info. 03:53:40 Duane Bennish: www.beachbouncer.com 04:01:54 VALENTINA CACCIA: Who want to be next? 04:02:33 robert moser: Thank you. Robert@RobertMoser.com 305.785.0297 04:05:05 Emmy PIQUET: Hi everybody. The regional council of Guadeloupe had lauched an INTERNATIONAL CALL FOR EXPRESSION OF INTEREST : "Establishment of an air quality measurement network for detecting gases resulting from Sargassum seaweed decomposition on the coasts of Caribbean countries". This project is part of the Caribbean program against Sargassum (SARG’COOP), and whose first formalization meetings started during the international conference on Sargassum, which brought together the best national and international experts, representatives of 22 countries and states involved, in October 2019 in Guadeloupe.The call for expression of interest aims to identify countries that would be interested in the establishment of an air quality measurement network for hydrogen sulphide and for ammonia on their territories. It is also about networking this Caribbean-wide air quality monitoring. Please contact me if you want any information about this project : epiquet@cr-guadeloupe.fr 04:07:32 Emmy PIQUET: Unfortunately I have to leave you. Thank you all! 04:08:44 Duane Bennish: That was very interesting. Thank you. 04:10:47 Maria Josefina Olascoaga: I have to go soon …. Thank you all! 04:12:10 VALENTINA CACCIA: Thank you Jose 04:12:31 VALENTINA CACCIA: Don’t be shy! Express your ideas 04:13:08 alain duran: Thank you to all the presenters and organizers. Excellent webinars (both 1 and 2). Very informative. 04:14:05 Ann Pienkowski: Thanks to all the presenters and organisers. And those who have asked very interesting questions. I have found it all fascinating, and learnt so much. My interest, as Secretary of the UK Overseas Territories Conservation Forum's Wider Caribbean Working Group is to share information amongst our members, and I will certainly be making them aware of your 2 webinar recordings. 04:14:32 Mario Gutierrez, P.E. LEED AP: Very informational webinar. Thank you to the organizers and participants. Mario Gutierrez 04:15:13 Emilio Lopez: Thank you, Mario! 04:20:48 Martin Sherman: can you please describe how organic arsenic effects things differently than non-organic arsenic? 04:28:28 Pablo Aguilera: Sargassum washing up on the beach is a natural extraction process and all the animals living in the sargassum perish. Solution is to extract it while it is floating in a manner that minimizes the effects to what is living there! 04:32:40 Amanda Oehlert: Thank you for the interesting discussion. I have another meeting to jump to. Looking forward to the continued conversations. 04:34:22 Martin Sherman: I must dash in a moment. Thank you, everyone! 04:41:24 Maria Josefina Olascoaga: Thanks Valerie 04:42:03 Valerie Barbosa French Embassy in Mexico: https://www.regionguadeloupe.fr/fileadmin/Site_Region_Guadeloupe/actus/appels_a_projets/2020_CEI_-_establishment_of_an_air_quality_measurement_network_VF.ENG-CIL.pdf 04:42:16 Valerie Barbosa French Embassy in Mexico: Here is the information on the call
