01:35:43 Donna Murphy: hi, Donna and Frank Murphy from Lake Waukewan 01:35:44 Tim Whiting: Tim & Anne Whiting 01:35:47 Mindy: Mindy & Kevin Pobst - Haunted Lake 01:36:11 Cynthia Covalucci: Hi! Cindy, Locke Lake Barnstead 01:36:30 Krystal Costa Balanoff: Haunted lake sounds scary! 01:38:36 Dennis & Maureen Card, Winnepocket: Dennis and Maureen Card from Lake Winnepocket. Hello! 01:43:18 Krystal Costa Balanoff: Don't forget to submit your questions and comments through the chatbox as we go. Amanda is going to cover a lot of excellent information! 01:52:20 Marko: What type of organism creates 'red tide'. Does it occur only in marine environments? Does it occur on the NH coast - or does it need warmer seas? 01:54:32 Jessica: Microscopic algae are single-celled plants that live in the sea. Occasionally, the algae grow very fast or "bloom" and accumulate into dense, visible patches near the surface of the water. Some species of phytoplankton contain reddish pigments, and an intense bloom of these species can make the water appear to be colored red. The term "Red Tide" is a common name for such a phenomenon. 01:54:57 Jessica: NH DES Red Tide FAQ Page: https://www.des.nh.gov/organization/divisions/water/wmb/shellfish/faq_redtide.htm 01:57:09 Krystal Costa Balanoff: Thanks Jessica! Excellent info. "Red tide" is specific to marine environments and does occur in NH. 01:59:03 Jim: what is the green cotton candy? 01:59:55 Krystal Costa Balanoff: THATS SO COOL 02:00:54 Jessica: Billowy masses of what looks like cotton candy are typically Filamentous algae 02:01:17 Alexander Amann: Do Picoplankton congregate in a great enough density to cause blooms and/or toxicity that is harmful? 02:02:22 Jessica: Filamentous algae fact sheet: https://nhlakes.org/wp-content/uploads/4-Lake-Concerns-Water-Quality-Green-Cotton-Candy-Like-Growth-NH-LAKES.pdf 02:02:39 Krystal Costa Balanoff: Great question Alexander - we will ask Amanda at the end! 02:04:54 Krystal Costa Balanoff: The stick test is highly scientific ;) 02:06:03 Alexander Amann: Is green filamentous algae a precursor to a HAB? Is excess nutrient input to blame, and which ones? 02:07:17 Andrea LaMoreaux: For those of you in areas experiencing thunderstorms, if you lose power, as long as Amanda doesn't lose power we will post the recording on our website as soon as we can this evening! 02:08:19 Krystal Costa Balanoff: Hi Alexander, not necessarily. Filamentous green algae don't always correlate to excess nutrients and are not an indicator of future HABs. However, reducing phosphorus inputs is an important approach to reducing plant growth, including algae! 02:13:13 Krystal Costa Balanoff: Do you have any slides for the end or just Q/A? If you do have slides maybe slack them to me just in case 02:13:39 Owen Bastille: Is NH Lakes and NHDES working with Dartmouth College's Cottingham Lab on Cyanobacteria? 02:15:22 iPad: can we prevent Cyanobacteria ? 02:15:28 Marko: Do you know how many people/pets have been hospitalized in NH during the past five years? 02:15:48 Krystal Costa Balanoff: NH LAKES works to educate property owners about ways to live in a more lake-friendly way through our LakeSmart Program. Communities working together to create this new conservation ethic can ensure the health of our lakes for future generations. But, we do not work with cyanobacteria research directly. I'll ask Amanda about NHDES involvement with this lab. 02:17:24 Tom O'Brien: Are nutrients like phosphorus and nitrogen the major cause or trigger for a bloom to occur? 02:18:34 Mindy: If phosphorous and nitrogen are implicated, do cesspools appear to have an impact? 02:18:47 Alexander Amann: Don't forget UNH Cooperative Extension's Lakes Lay Monitoring Program! 02:20:52 Krystal Costa Balanoff: All good questions! I'll ask Amanda at the end. Though, sometimes blooms occur in cool, clear, low nutrient lakes for seemingly no reason. 02:22:07 Pamela Roller Dorsett: thank you 02:25:05 Douglas Summerton: What again kills dogs 02:26:34 Jessica: Hi Douglas, I believe Amanda said the Anatoxin was associated with harming pets in the water 02:27:14 Owen Bastille: How many of these blooms also happen in slow moving coastal rivers? 02:27:25 Marko: Are cyanobacteria sensitive to pH? 02:31:55 Pamela Roller Dorsett: Douglas, Amanda also stated that you should wash your pets after being in contaminated water, so the pets do not ingest more by their grooming. 02:35:23 Owen Bastille: What types of toxins do picocyanobacterial? 02:35:28 Drew’s iPad: any good water temp reporting links 02:36:02 Andrea LaMoreaux: So many great questions! If we don't get to them all tonight we will follow up with information. 02:36:02 Krystal Costa Balanoff: Picoplankton produce microcystins 02:37:06 Jim: Is there any correlation between the occurrence of bladder and Cyanobacteria? 02:37:28 Jim: Bladderwort 02:38:52 Donna Murphy: Thank you Amanda. Grsat 02:39:17 Donna Murphy: sorry, thanks a Amanda great presentation. 02:39:53 Krystal Costa Balanoff: Hi Jim, bladderwort occur naturally in NH's lakes and are not an indicator of nutrient concerns. You may see LOTS of bladderwort some years, and very little in other years due to temperature and precipitation. But, they are plants and thus the things that make lake plants grow can also encourage certain species of cyanobacteria to grow. 02:41:05 Jim: Thanks Krystal 02:41:56 Andrea LaMoreaux: Wow! So great to talk with an expert on this! 02:42:39 Kevin McCusker: Thank you all! 02:43:04 Owen Bastille: Thank you!! 02:43:26 Thomas Jacobson: Thank you all!! 02:43:45 Pamela Roller Dorsett: thank you 02:43:49 donna: thank you 02:43:53 Sandy Crystall: Thanks Amanda. Great presentation! Good to see you! 02:44:00 Jim: Thank you everyone. Hope we have more of these 02:44:02 Susan Showalter: Thank you very informative 02:44:23 Steve Landry: Thank you, women. 02:44:30 Daniel: Thank you!! This was awesome! 02:44:45 Krystal Costa Balanoff: Thanks Amanda! And thanks to you all for the wonderful questions and passion for our lakes!
