Introduction
This cruise report provides a summary of scientific activities aboard the SSV Corwith Cramer
during Cruise C-268A (August 8, 2016 – August 15, 2016). This was an SEA Invitational Sail,
during which invited participants sailed from Cádiz, Spain to Alicante, Spain, with brief
overnight stops in Málaga and Cartagena. While onboard the ship, the participants shared the
experience of sailing and shipboard life and learned about SEA and SEA’s academic programs.
True to SEA and SEA Semester, they became part of the crew and stood watch, handled sail,
navigated, steered, performed boat checks, and helped in the science lab and galley. Scientific
sampling was conducted throughout the cruise in easternmost Atlantic Ocean and western
Mediterranean Sea waters.
Data Description
This section provides a record of data collected aboard SSV Corwith Cramer Cruise C-268A, which departed
from Cádiz, Spain and voyaged through the Straits of Gibraltar and along the Spanish Mediterranean coast for
approximately 475nm before ending in Alicante, Spain (Figure 1).
During the 8-day cruise, we occupied three oceanographic stations. We collected biological
samples with the neuston net at the first station, conducted a vertical meter net tow at a second
station, and deployed styrofoam cups at a third oceanographic station to evaluate the effects of
water pressure on cup shrinkage (Table 1). Additionally, we continuously sampled water depth

and sub-bottom profiles (CHIRP system), oceanographic currents (ADCP), and sea surface
temperature, salinity, and chlorophyll in-vivo fluorescence with the seawater flow-through
system. Wind speed and direction were also recorded. No CTD, hydrocast, or sediment
sampling deployments were made. Data summaries of the neuston tow sample are given in
Tables 2 and 3. Voluminous ADCP, CHIRP, and flow-through data are not fully presented
here. All unpublished data can be made available by arrangement with the SEA data archivist
(contact information, p. 2). The brief summary of C-268A data contained in this report is not
intended to represent final data interpretation and should not be excerpted or cited without
written permission from SEA.

2 Station C268A-002-MN comprised a vertical meter net tow, conducted while the ship was hove to. Mostly clear gelatinous organisms
were recovered, including siphonophores and small salps. Clear copepods, chaetognaths, and fish larvae were also present. The
recovered sample was not quantitatively analyzed, and no 100-count of zooplankton was conducted.
3 Station C268A-003 was a styrocast, during which styrofoam cups were deployed on the hydrowire to a depth of 2000m in order to
test the effects of pressure on cup shrinkage. No additional oceanographic data were collected at this station.

Data Description C269
The cruise track for C-269 (Figure 1) departed from Barcelona, Spain and concluded in Las
Palmas, Gran Canaria 41 days later. During the nearly six-week voyage we had three port stops;
the first in Palma de Mallorca, Spain; the next in Cadiz, Spain and the third was a return to
Cadiz, Spain after a short sail in the Gulf of Cadiz that was thwarted by weather conditions.
Our cruise track traversed several major oceanographic provinces (Figure 1): a) the productive,
warm, salty waters of the NW Mediterranean Sea, b), the less productive, warm, less salty waters
of the SW Mediterranean Sea, c) the very productive, transitional waters of the Alboran Sea, d)
the productive, cool and less salty waters of the Gulf of Cadiz, and e) the less productive, cool,
salty waters of the sub-tropic, eastern North Atlantic.
We collected data with 120 individual deployments from 45 discrete geographic stations along
our cruise track. Comparison of the physical, chemical, biologic and geologic features of these
regions represented the major oceanographic theme of this Sea Semester.
1. Physical oceanographic studies focused on the distribution of surface and sub-surface (to
2000 m) water masses and the delineation of hydrographic boundaries. Specifically,
Modified Atlantic Water, Levantine Intermediate Water, Western Mediterranean Deep
Water, and the Western Mediterranean Transition Water. Outside the Mediterranean
basin we looked for ‘Meddies’ (sub-surface Mediterranean eddies).
2. Chemical oceanographic studies focused on the geographic and vertical distribution of
nutrients (phosphate and nitrate), extracted chlorophyll-a, coliform bacteria, and pH.
These chemical parameters were related to patterns in physical hydrography at various
scales: nearshore to offshore transitions, ocean fronts and eddies associated with island
passages, the Strait of Gibraltar, and water column stratification.
3. Biological studies focused on the geographic distribution of charismatic megafauna
(seabirds, sea turtles, flying fish, and marine mammals), several nektonic organisms
(lantern fish – Family Myctophidae, and gelatinous organisms >2cm – i.e Pelagia
noctiluca), meroplanktonic larvae including spiny lobster (phyllosoma) and eels
(leptocephali), the marine insect Halobates, and the density (mL/m2) and diversity (i.e.
Shannon-Weiner index) of the aggregate zooplankton community including pteropods.
4. Geological sampling focused on surface sediment samples collected from continental
shelf regions near each port stop. Patterns were related to coastal development and
distance from shore.
Sea surface temperature, salinity, fluorescence (chlorophyll-a and CDOM) and transmissivity
levels; along with barometric pressure, winds, bathymetry, and geographic position were
recorded continuously along the cruise track. Large-scale hydrography is summarized with
surface plots for some parameters (Figure 2a-c) other data is available upon request. Surface
samples (85) of nutrients (phosphate, nitrate), chlorophyll-a, and pH were collected every six
hours and in conjunction with all neuston net tows during the cruise track (Table 3). As part of
near-to-offshore transects and shipek grabs stations (see below) water samples were collected to
measure coliform bacteria as a indicator of human impacts in coastal settings (Table 4).
9
Additional Hourly Observations included the enumeration of seabirds, sea turtles, flying fish,
marine mammals, and floating plastic debris. Observations occurred only during daylight hours
0700-1900 for a period of 6 minutes each hour. Periodically, opportunistic sightings were also
recorded when notable megafauna or marine debris were present. Data available upon request.
But for the occasional eddy associated with the Almeria-Oran front and the Straits of Gibraltar
surface currents along the C269 cruise track were weak (< 500mm/s, or 1.0 knot) and variable in
direction. Regional examination of surface currents highlight the presence of eddies and
meanders near constricted passages or islands (Figure 3).
The density structure of the water column (maximum depth 2000 m) was determined using a
Seabird CTD with attached dissolved oxygen sensor (11 stations, Table 5). Vertical profiles of
chlorophyll-a and nutrients (phosphate, nitrate) and pH were determined using a 12-bottle
carousel equipped with a Seabird CTD and three auxiliary sensors: in situ chlorophyll-a
fluorescence, dissolved oxygen, and photosynthetic active radiation (PAR) (15 stations, Table 6).
Four water masses were tracked as revealed by profiles of temperature, salinity, dissolved
oxygen, and chlorophyll-a fluorescence as well as two sub-surface eddies or ‘meddies’ once
outside the Mediterranean (Figure 4a-d).
Surface plankton assemblages along with marine debris and tar balls were sampled regularly
with a neuston net (37 stations, 335 µm mesh, Table 7). Sub-surface plastic and zooplankton
communities were collected with a Tucker Trawl at a shallow depth of 5-10m (8 stations, 335
μm mesh, Table 8). Plankton assemblages at discrete depths (200m) were collected using a 1m
diameter Meter net (1 stations, 335 μm mesh, Table 9). In combination these myriad net
deployments reveal the vertical and horizontal distribution patterns of several nektonic
organisms (lantern fish – Family Myctophidae, and gelatinous organisms >2cm – i.e Pelagia
noctiluca), meroplanktonic larvae including spiny lobster (phyllosoma) and eels (leptocephali),
the marine insect Halobates, pteropods, and the density (mL/m2), diversity (i.e. Shannon-Weiner
index) and taxonomic composition of the aggregate zooplankton community in relation to
numerous environmental parameters (Table 10).
Routinely a phytoplankton sample was collected with a surface (~1-3m) drifted net (15 stations,
30cm frame, 63 µm mesh, Table 11) to determine the taxonomic composition of phytoplankton,
foraminiferans and radiolarians.
Eleven sediment samples were collected using a shipek grab ranging in depth from 40 to 340m
and sieved fro grain size analysis and sorted for benthic organism diversity related to human
impact as deduced via coliform bacteria counts (Table 12). Additional data available upon
request.
Final scientific work conducted aboard ship was the routine deployment of a secchi disc (14
stations, Table 13) to estimate the 1% light level.
Additional CTD, CHIRP, ADCP and biological data not reported here are available on request
through Sea Education Association (SEA) and the Chief Scientist. The information in this report
10
is not intended to represent final interpretation of the data and should not be excerpted or cited
without written permission from SEA.
As part of SEA’s educational program, undergraduates conducted independent oceanographic
research during the cruise. Projects explored regionally, relevant topics in the disciplines of
physical, chemical, and biological oceanography (Table 14). Student research efforts culminated
in a written report and public presentation to the ship’s company. These papers are available on
request from SEA.

Duplicate station numbers indicate multiple oceanographic deployments that either occurred concurrently in the same location
or were deployed sequentially in the same general location after the vessel was hove to. General Locations are categorized by
traditional oceanic biomes or significant geologic feature. Abbreviations for oceanographic equipment deployed are: NT –
Neuston Tow, TT – Tucker Trawl net, MN – Meter Net tow, PN – Phytoplankton Net, CTD – conductivity, temperature, and
depth profilers, HC – Hydrocast with 12 Niskin bottles and CTD, SG – Shipek Grab, and SD – Secchi Disc. * These stations
occurred in Moroccan waters (EEZ) and were for training purposes only, no data was collected.

Surface water samples were collected using a clean, seawater flow-thru system (intake ~ 1-3m depth) with in-line
temperature, salinity and in vivo chlorophyll-a, fluorescence sensors. Discrete water samples were collected for
phosphate (PO4) analysis, measured by colorimetric analysis with an Ocean Optics Chem2000 digital
spectrophotometer; and extracted chlorophyll-a (Chl-a) concentrations, measured with a Turner Designs Model 10-
AU Fluorometer following methods outlined in Parsons, Maita and Lalli, A Manual of Chemical and Biological
Methods for Seawater Analysis, Pergamon Press 1984. Chlorophyll-a samples were filtered through 0.45 µm filters.
A blank space indicates that no sample was collected for that analysis.

Coliform bacteria colony counts were based on EPA Coliquant Test kits incubated at ambient air temperature for two days. Plates were photographed and colony
growth was counted under a dissecting microscope at 24hrs and 48hrs. Surface water samples were collected using a clean, seawater flow-thru system (intake ~
1-3m depth). Near-bottom and sub-surface water samples collected with niskin bottles rigged above shipek grabs and with hydrocast deployments.

Tow area was calculated using distance in meters between successive (every minute) GPS positions. Net opening was 1.0 m wide by 0.5 m tall with a net mesh
of 335 µm. Zooplankton density is recorded as wet volume displacement per tow area (ml/m2). Eel larvae (leptocephali), spiny lobster larvae (phyllosoma), and
Lantern fish (Family Myctophidae), were sorted from net contents and recorded as numbers caught per tow. Micronekton, gelatinous micronekton, and plant
material was removed using a 1 cm mesh sieve and biomass (ml) or length (cm) was recorded. Floating plastic was also removed from net contents, sorted as
pellets (none collected entire cruise) or pieces and recorded as numbers collected per tow. Floating tar was sorted from the nets contents and recorded present or
absent (none collected entire cruise). Qualitative description of micronekton removed from the zooplankton biomass is provided, and when available biomass
(ml) and length (cm) of specimens are recorded
