Delcan\u00a0(1994b), reported seagrass beds along the west coast at Shermans, Six Men\u2019s Bay, Speightstown\u00a0and Brighton; along the southwest coast at Bridgetown, Hastings, Rockley, Worthing, St.Lawrence, Dover, Maxwell, Welches, Oistins, Enterprise and Atlantic Shores of Barbados; and\u00a0along the east coast at Bath and Conset Bay.<\/p>\n<p>\u201cThere is evidence that the quality of the local coastal marine water is deteriorating due to increased sedimentation, eutrophication and sewage pathogens, localised increases in temperature, decreases in salinity, and perhaps increases in toxins (Delcan, 1994a). There is also evidence to suggest that grazing by fish and sea urchins is an important mechanism for recycling nutrients within the beds. Heavy fishing pressure that results in the removal of these animals can therefore also negatively affect the vibrancy seagrass beds. Physical damage in coupled with poor water quality will negatively impact on the vibrancy of seagrass beds. It is therefore probable that the local seagrasses are being impacted negatively by many coastal activities and land based sources of pollution and urgent attention must be given to ways of minimizing these impacts\u201d<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><a name=\"context\"><\/a><\/p>\n<p style=\"text-align: center;\">&#8212;&#8211;<\/p>\n<p>Most of what I have to offer on these pages are not recent observations of seagrasses at Barbados, but historical observations over the period 1969 to 2015.

We were based at the Bellairs Research Institute (McGill University) located in Holetown, Barbados.<\/p>\n<p>&nbsp;<\/p>\n<p>That venture led to my attending a 6 week summer course in Tropical Marine Biology at the Bellairs Research Institute (BRI)\u00a0 in the summer of 1966. As it was drawing to a close,\u00a0 the Director (and founder) of BRI, Prof John Lewis\u00a0(McGill University) asked if I would be interested in doing\u00a0 PhD research at Bellairs &#8220;on seagrasses&#8221;.<\/p>\n<p>At the time, there was very little known about tropical seagrasses\u00a0 and he would allow me to choose the particular direction of the research. I had just completed a MSc at McGill on Arctic cod, and had spent the summers of 1961-1965 as a research assistant on an experimental 37 ft fishing boat in the western Arctic&#8230; I loved it, but a lot of the time was spent stuck in ice packs.\u00a0 So I was looking around for a more predictable alternative field-wise for my PhD research and\u00a0 my interests were shifting from marine fish to marine plants, so&#8230; I accepted Prof. Lewis&#8217;s offer and began my research in July of 1967.<\/p>\n<p>My focus was on nutrient cycling and answering the question, &#8220;How is turtle grass (<em>Thalassia testudinum<\/em>) so productive in nutrient poor topical waters?&#8221; In reading all I could about seagrasses over the intervening year, I was intrigued by the suggestion of the marine microbiologist EJF Wood (1965) that &#8220;[the seagrass] Zostera seems to be confined to areas where sulphide is present possibly because of the release of phosphate brought about by sulphate reduction&#8221;.*<br \/>\n* <small>EJF Wood, 1965. <a href=\"https:\/\/archive.org\/details\/marinemicrobiale0000ejfe\/page\/n9\/mode\/2up\">Marine microbial ecology<\/a>, 243 pages, London: Chapman &amp; Hall, pp108-109<\/small><\/p>\n<div id=\"attachment_5218\" style=\"width: 310px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/versicolor.ca\/barbados\/wp-content\/uploads\/2026\/02\/NinaDave.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-5218\" class=\"size-medium wp-image-5218\" src=\"http:\/\/versicolor.ca\/barbados\/wp-content\/uploads\/2026\/02\/NinaDave-300x265.jpg\" alt=\"\" width=\"300\" height=\"265\" srcset=\"https:\/\/versicolor.ca\/barbados\/wp-content\/uploads\/2026\/02\/NinaDave-300x265.jpg 300w, https:\/\/versicolor.ca\/barbados\/wp-content\/uploads\/2026\/02\/NinaDave-768x680.jpg 768w, https:\/\/versicolor.ca\/barbados\/wp-content\/uploads\/2026\/02\/NinaDave.jpg 894w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-5218\" class=\"wp-caption-text\">My spouse assists\/directs me &#8220;in the lab&#8221;, 1968<\/p><\/div>\n<p>So I set out to test that hypothesis on <em>T. testudinum<\/em>\u00a0 in Barbados. Could the high productivity be explained by release of phosphorus in the sediments stimulated by seagrass-induced reducing\u00a0 (anoxic, anaerobic) conditions?<\/p>\n<p>I had 3 years in total to complete my field research. After about 15 months, progress was proving to be slow and I decided to switch to a more predictable path of research. I would\u00a0 do formal (quantitative) surveys of seagrass beds and associated benthic flora and fauna around Barbados, and around the island of Carriacou (Grenada); I included the latter\u00a0 because seagrass beds there were much more extensive\u00a0 than in Barbados and more typical of the Caribbean broadly, especially the meadows that occur in the lagoons behind barrier reefs of the east coast of the island.<\/p>\n<p>I\u00a0 completed that field work within a year, but in the process figured out a new tack on the nutrient issue*, so I again pursued that avenue, completing the nutrient research by the beginning of 1970. I wrote my thesis on &#8220;<a href=\"https:\/\/escholarship.mcgill.ca\/downloads\/jh343t00x\">The origin of nitrogen and phosphorus for growth of the marine angiosperm <em>Thalassia testudinum&#8221;<\/em><\/a>\u00a0I published 3 papers on observations I made as components of the survey**, but except for some qualitative description of seagrass beds in my thesis, and in the &#8220;blowout paper&#8221;, the surveys themselves were not published.<br \/>\n*<small>On the new tack. In the course of the surveys I observed big diffs. in the length (height) of <em>T. testudinum<\/em> blades between diff. sites. I wondered if the length was a function of the growth rate; J. Zieman had published a new, simple method of measuring leaf growth, I used it and indeed found a high correlation between length and growth rate. So then I could use leaf length as a measure of growth rate and look for relationships between growth or production\/yield and various measures of nutrients in the sediments&#8230; To my surprise I found relationships between yield and sediment nitrogen but not with sediment phosphorus&#8230;See <a href=\"https:\/\/link.springer.com\/article\/10.1007\/BF00347435\">The origin of nitrogen and phosphorus for growth of the marine angiosperm\u00a0<em>Thalassia testudinum<\/em><\/a><\/small><small>, Patriquin, D.G. 1972. <em>Marine Biology<\/em> 15: 35-46, and\u00a0<strong><a href=\"https:\/\/link.springer.com\/article\/10.1007\/BF00347847\"><small>Nitrogen fixation in the rhizosphere of marine angiosperms<\/small>\u00a0<\/a><\/strong>Patriquin, D.G. and R.

My last visit to Bath, facilitated and accompanied by Elon Cadogan of CORALL,\u00a0 occurred in 2025, 58 years after 1967.<a name=\"use\"><\/a><\/p>\n<p>As matters stand in early 2026, we are not visiting Barbados this year because of medical issues, but that&#8217;s giving me time to get a good start on the &#8220;Barbados seagrass data&#8221;, and we have already reserved a place to stay again in 2027.<\/p>\n<p>So bit by bit I will post the Barbados seagrass data on this website as I am able to process them&#8230; It&#8217;s a job I absolutely love to do, each item recalling earlier days&#8230; and allowing the experience all over again, in Bim or not.<\/p>\n<p>ON USE OF THE DATA<\/p>\n<p>These &#8220;seagrass data&#8221; (including all photos), processed\/analyzed to various degrees can be utilized by anyone with an interest in them, no need to request permission. I will ensure as I can that the website remains available at least 5 years beyond my passing; regardless most or all of the contents should\u00a0 remain available on the <a href=\"https:\/\/web.archive.org\/web\/20251115000000*\/http:\/\/versicolor.ca\/barbados\/\">web archive<\/a>. Perhaps a scientific paper or two will emerge in the process (as for <a href=\"https:\/\/versicolor.ca\/sandylakebedford\/2025\/02\/20\/unusually-late-bga-bloom-in-sandy-lake-bedford-reported-in-harmful-algal-news-unesco-20feb2025\/\">Sandy &amp; Environs<\/a>) and perhaps I will compile one final, comprehensive Technical Report on the Barbados seagrass. Or not. At best we can be certain only about the present.<\/p>\n<p>&#8211; <em>david p<\/em> Feb 6, 2026.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ObsSG: Observations on Seagrasses Navigation Barbados Fringing Reefs &amp; Seagrass Beds Natural History Perspectives of a Visiter &#8211; ObsSG\u00a0(This Page, a top-level page) Other top-level SG Observation Pages: &#8211; ObsSG-Bath\u00a0(Seagrass at Bath) &#8211; ObsSG-SL (Seagrass at St.Lawrence) Also view on &hellip; <a href=\"https:\/\/versicolor.ca\/barbados\/obssg\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":200,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-5266","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/pages\/5266","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/comments?post=5266"}],"version-history":[{"count":86,"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/pages\/5266\/revisions"}],"predecessor-version":[{"id":9121,"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/pages\/5266\/revisions\/9121"}],"wp:attachment":[{"href":"https:\/\/versicolor.ca\/barbados\/wp-json\/wp\/v2\/media?parent=5266"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
