"Colonies of Porites astreoides corals (5-20 cm diameter, 30-90 g wet weight)
were removed from 3-9 m depth on the Bermudian reefs Hog Breaker (N 32
27.5\\u2019 W 64 49.8\\u2019), an unnamed reef (N 32 26.042\\u2019 W 64
49.248\\u2019), and Three Hills Shoal (N 32 41\\u2019 W 64 73.3\\u2019) in July
2013. Ten colonies were taken from each site in compliance with the Bermuda
Institute of Ocean Sciences (BIOS) Collection and Experimental Ethics Policy
and were considered Limited Impact Research and as such a collection permit
was not required. The colonies were immediately placed in collection bags at
depth, sealed and transported in a large collection cooler (greater than 1 h)
to the laboratory.\\u00a0 At BIOS, the colonies were allowed to acclimate to a
mesocosm housing and held in aerated, outdoor fiberglass mesocosms with a
flow-through seawater system fed with reef water for two (Three Hills Shoal
Reef colonies) or 15 days (all other colonies) prior to the start of the
experimental period.\\u00a0
For the experiment, the mesocosms consisted of nine, 30 L static aquaria that
were set up as previously described (de Putron et al. 2010). Inshore water
from 20 meters off shore and one meter in depth was used to fill the aquaria
and was pumped through a BIOS flow-through sample system that consisted of a
coarse mesh filter and holding tanks followed by a step filtration system of
50 um, then 5 um, to remove larger organisms including some planktonic
grazers. Mesocosms were then left static for the 12-day experiment. Mesocosms
were randomly arranged to consist of three control, three mucus addition, and
three coral mesocosms, with artificial lights providing 61 mol quanta m-2 s-1
photosynthetically active radiation during sunlight hours consistent with the
low end of known compensation ranges (3-233 mol quanta m-2 s-1 according to
Mass and colleagues (2007) to minimize bleaching. Mesocosms were covered with
a transparent plastic film cover and aerated with an air wand bubbler (de
Putron et al. 2010). Water was collected from the mesocosms via a syringe-
siphon system using silicon tubing.\\u00a0 Inline, combusted GF/F filters
(Whatman, Maidstone, UK) were attached for samples intended for dissolved
organic carbon (DOC) analysis. The reef water temperature, salinity, and
conductivity in all mesocosms was monitored daily throughout the experiment
using a YSI Professional Plus probe (Yellow Springs, Ohio).\\u00a0
Over the course of 12 days, the mesocosms were subjected to one of three
conditions: coral (presence/absence of colonies), mucus additions or control
(no additions).\\u00a0 For the coral mesocosms, the experimental corals (four
colonies per mesocosm, three mesocosms) were placed within the mesocosms on
days 0 through 4 and removed after water sampling on day 4. Corals were
removed for 48-hour until after the sampling procedure on day 6, where they
were held in running seawater similarly filtered as in the mesocosms, and
reintroduced back into their respective mesocosms from days 6 to 10 and
removed again after the sampling procedure on day 10. P. astreoides colonies
were not fed over the course of the 12-day experimental period. For the mucus
addition mesocosms, mucus was extracted from P. astreoides colonies (n = 18)
that were not utilized in the experiment and were maintained in a separate,
flow-through seawater tank.\\u00a0 These corals (n=18) were taken into the lab
and inverted on a funnel to collect mucus for 2 h, a timeframe determined from
a preliminary experiment, and the corals returned to the holding aquaria with
flow through seawater. Mucus from the additional colonies was pooled and 5 ml
was added to each mucus addition mesocosm on days 0.2, 2, 6 and 8.\\u00a0 Mucus
from the experimental corals (n = 12; named corals A-L from coral tanks 4, 5
and 6) was sampled for community composition prior to day 0, as well as at the
end of day 4 and at the end of day 10 of the experiment.\\u00a0 For the latter
two timepoints, the corals were removed from the experimental mesocosms for 48
hours.\\u00a0
Seawater samples (50 ml) for cell counts and fluorescence in situ
hybridization (FISH) analyses were taken daily from all mesocosms, fixed with
formalin to a final concentration of 10% in the dark for 20 min, and stored at
-80C.\\u00a0 Samples were thawed and 3-5 ml were filtered onto Irgalan Black
stained 25 mm, 0.2 um polycarbonate filters (Nucleopore, Whatman) under gentle
vacuum (100 mmHg) and stained with 1 ml of 0, 6-diamidino-2-phenyl
dihydrochloride (5 ug ml-1, DAPI, SIGMA-Aldrich, St. Louis, MO) (Porter and
Feig 1980). The filters were mounted onto slides with Resolve immersion oil
(high viscosity) (Resolve, Richard-Allan Scientific, Kalamazoo, MI) and stored
at \\u201320 degrees celsius. Slides were then enumerated using an AX70
epifluorescent microscope (Olympus, Tokyo, Japan) under ultraviolet excitation
at 100x magnification. At least 500 cells (10 fields) were counted for
picoplankton abundance.\\u00a0\\u00a0 \\u00a0
FISH was utilized to quantify the abundance of the major picoplankton
phylotypes present in the seawater and mucus, and was conducted using
previously published protocols and Cy3 labeled probes (Parsons et al. 2014).
The bacterial and archaeal groups quantified included the SAR11 clade (152R,
441R, 542R, 732R probes), Alteromonas spp. (AC137R), Vibrio spp. (127R),
Rhodobacteracea (536R), Euryarchaeota (Eury806) and Thaumarchaeota (Cren537).
Fixed seawater samples (3\\u20135 ml) were filtered onto 25 mm, 0.2 um
polycarbonate filters and stored at \\u221220 degrees celcius with desiccant.
Quarter filters were washed in 95% ethanol and then probed according to
previous protocols (Morris et al. 2002; Parsons et al. 2011, 2014). The cell
abundances of the picoplankton phylotypes mentioned above were then determined
using image analysis (Parsons et al. 2011, 2014). Detection of Cy3-positive
cells and their ratio to DAPI-positive cells was aided by image analysis using
an Olympus AX70 microscope (Olympus, Japan) equipped with a Toshiba 3CCD video
camera (IK-TU40A Toshiba, Japan), a computer assisted frame grabber and
appropriate dichroic filters (Morris et al. 2002; Carlson et al. 2010). Brief
exposure times of 1 and 5 seconds were used for DAPI and Cy3 image channels,
respectively.\\u00a0 Cy3 images were segmented with Image Pro Plus software
(Media Cybernetics, Bethesda, MD) and overlaid onto corresponding segmented
DAPI images (Parsons et al. 2014). Objects with overlapping signals in both
Cy3 and DAPI images were counted as probe positive. The negative control was
determined similarly and subtracted from the positive probe counts to correct
for autofluorescence and non-specific binding.\\u00a0 (For Grazing Rates
Processing, see below)
Seawater picoplankton biomass for nucleic acids was taken from all
experimental mesocosms on days 0, 2, 4, 6, 8, 10 and 12 of the experiment, and
from coral mucus extracted from the experimental corals on days 2, 4, and 10
and processing followed a method modified from Giovannoni and colleagues
(1990, 1996). 500 ml of water or 1 ml of coral mucus was filtered through a 47
mm, 0.2 um pore filter under gentle vacuum (100 mm Hg), placed into a 4 ml
cryovial and stored in 1 ml of sterile sucrose lysis buffer (20 mM EDTA, 400
mM NaCl, 0.75 M sucrose, 50 mM Tris.HCl) at -80 degrees celsius. For DNA
extractions of the tissue, mucus and coral samples, sodium dodecyl sulfate to
1% and proteinase K to 200 ug ml-1 were added to the sample and incubated at
37 degrees celsius for 30 min and then at 55 degrees celsius for 30 min. The
lysates were extracted with an equal volume of
phenol:isoamylalcohol:chloroform (25:1:24) followed by two subsequent equal
volumes of isoamylalcohol:chloroform (1:24). The DNA was purified by
precipitation using sodium acetate (3M) and isopropanol (100%) for at least 1
hour at -20oC and centrifuged at room temperature for 30 min at 20,000 x g.
The resulting pellet was washed with 80% ethanol, vortexed for 30 s and
centrifuged at 16,000 x g for 10 min. The pellet was dried and stored at
-20C.\\u00a0 (See below for Microbial Processing description.)
Seawater samples were analyzed for macronutrients (nitrate + nitrite, nitrite,
ammonium, ortho phosphate, and silicic acid)\\u00a0 at Oregon State University
using a continuous segmented flow system consisting of a Technicon
AutoAnalyzer II (SEAL Analytical) and an Alpkem RFA 300 Rapid Flow Analyzer
(Alpkem) as conducted previously (Apprill and Rapp\\u00e9 2011). DOC was
determined via high temperature combustion on a modified Shimadzu TOC-V
(Shimadzu Scientific Instruments, Columbia, MD) (Carlson et al. 2010). Flow
cytometry was performed on 1 ml seawater preserved to a final concentration of
4% paraformaldehyde to enumerate pigmented picoeukaryotes, Synechococcus, and
non-pigmented picoplankton using methods described in Apprill and Rapp\\u00e9
(2011). High and low DNA-containing cells were enumerated following SybrGreen
staining. The ANOVA and Tukey\\u2019s HSD statistics were conducted as
described below.";

"Description from NSF award abstract:
Reef-building corals are in decline worldwide due in part to climate change and other human activities, and it is becoming increasingly important to understand what aspects of coral biology are degraded by environmental stress which then leads to coral mortality. It is now widely known that corals harbor communities of bacteria and archaea that are believed to play important roles in maintaining the health of their hosts, but we lack any appreciable understanding about the identity of the microbial associates regularly residing within healthy, reef-building corals. This project asks the central question: do reef-building corals harbor fundamental or persistent microbial associates that are symbiotic within their tissues? In order to address this hypothesis, the investigator will assess the identity of the bacterial and archaeal microbes using a variety of molecular and microscopy approaches that includes the identification and localization of a widespread group of coral bacterial associates belonging to the genus Endozoicomonas. The results of this study will then be used to develop additional questions about the role of these microbial associates in nutrient cycling and how they contribute to the health and survival of corals.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
