anonymous 16352 Water column data on dissolved inorganic carbon, total alkalinity, nutrients and hydrographic parameters in the Benguela Upwelling System during RV Meteor cruise M153 and RV Sonne cruise SO285 As part of the BMBF funded project TRAFFIC (Trophic Transfer Efficiency in the Benguela Current), water column samples were collected from the CTD/Rosette sampler during RV Meteor cruise M153 and RV Sonne cruise SO285. Dissolved inorganic carbon (DIC) Total Alkalinity (TA) were measured on board using the VINDTA 3C system (MARIANDA, Germany, www.marianda.com) as a combined TA and DIC titration stand. TA was determined by titration of seawater with hydrochloric acid (0.1 N HCl), while DIC was measured coulometrically. During cruise M153, DIC was measured with a cavity ringdown spectrometer (Picarro G2201-I, 1510CFIDS2047_v1.0) attached to a Liaison A0301 and an AutoMate Prep device. Both the VINDTA 3C and Picarro systems were calibrated using Certified Reference Material provided by A. Dickson (Scripps Institution of Oceanography, La Jolla, CA, USA). Nutrient samples were filtered through disposable syringe filters (0.45 µm) after sampling, filled pre-rinsed 50 ml PE bottles and kept frozen at -20°C until on-shore analysis using a continuous-flow injection system (Skalar SAN plus System) according to methods described by Grasshoff et al. (1999). 16360 https://doi.org/10.1594/PANGAEA.957862 2023-04-27T07:04:43+0000 2023 14104 18287 18516 18515 18514 18513 18512 18511 18510 18509 18508 18507 18506 18505 18504 18503 18502 18501 18500 18499 18498 18497 18496 18495 18494 18493 18492 18491 18490 18489 18488 18487 18486 18485 18484 18483 18482 18481 18480 18479 18478 18477 18476 18475 18474 18473 18472 18471 18470 18469 18468 18467 18466 18465 18464 18463 18462 18461 18460 18459 18458 18457 18456 18455 18454 18453 18452 18451 18450 18449 18448 18447 18446 18445 18444 18443 18442 18441 18440 18439 18438 18437 18436 18435 18434 18433 18432 18431 18430 18429 18428 18427 18426 18425 18424 18423 18422 18421 18420 18419 18418 18417 18416 18415 18414 18413 18412 18411 18410 18409 18408 18407 18406 18405 18404 18403 18402 18401 18400 18399 18398 18397 18396 18395 18394 18393 18392 18391 18390 18389 18388 18387 18386 18385 18384 18383 18382 18381 18380 18379 18378 18377 18376 18375 18374 18373 18372 18371 18370 18369 18368 18367 18366 18365 18364 18363 18362 18361 18360 18359 18358 18357 18356 18355 18354 18353 18352 18351 18350 18349 18348 18347 18346 18345 18344 18343 18342 18341 18340 18339 18338 18337 18336 18335 18334 18333 18332 18331 18330 18329 18328 18327 18326 18325 18324 18323 18322 18321 18320 18319 18318 18317 18316 18315 18314 18313 18312 18311 18310 18309 18308 18307 18306 18305 18304 18303 18302 18301 19623 21413 17459 17458 Rixen, Tim; Siddiqui, Claire (2023): Water column data on dissolved inorganic carbon, total alkalinity, nutrients and hydrographic parameters in the Benguela Upwelling System during RV Meteor cruise M153 and RV Sonne cruise SO285 [dataset].
